Are there more wheels or doors in the world

When New Zealander Ryan Nixon asked Twitter users whether they thought there were more doors or wheels in the world, he probably didn’t expect to start an online war. But that’s exactly what happened after March 5, as social media users, statisticians, and mathematicians all tried to solve this seemingly unsolvable riddle.
Car insurance comparison super app Jerry is here to end the debate. As experts on all things car-related, we know a thing or two about wheels—and we’re here to prove that, yes, there are more wheels than doors in the world.

How many doors are there in the world?

Without getting too deep into the numbers, we can estimate that there are as many as 33 billion doors in the world, between houses, apartment buildings, vehicles, and the cabinets, closets, and other compartments inside them.
That’s a lot of doors! But how does it compare to the number of wheels? Let’s take a look.

How many wheels are there in the world?

Okay, it’s pretty much impossible to give an exact count of all the wheels that exist in the world. After all, we’re making more all the time, and have been ever since the first wheel was invented around 3,500 BCE.
About 152,971 passenger cars were manufactured in 2020 alone (that’s 17 a second!), and even Hot Wheels produces close to 15 cars every second! And that’s not taking into account all of the wheels turned out each day for bicycles, shopping carts, airplanes, office chairs, and non-Hot Wheels toys.
To get a decent estimate of the number of wheels in the world, let’s break down the different types of wheels.

Cars

The first car, the three-wheel Benz Patent Motor Car, was invented in 1886—and ever since, wheels have been a part of life.
There are 1.446 billion cars in the world today. Multiply that by four, the average number of wheels on a standard modern passenger car, and you’re looking at 5.784 billion wheels.
“But, wait,” you say (in a smug, anti-wheel voice). “Don’t most cars have the same number of doors and wheels?”
And it’s true: most of the cars manufactured in the world are sedans, four-door SUVs, and other cars with an apparent wheel-to-door ratio of 4:4. For instance, the Toyota Corolla, the best-selling car of all time with 37.5 million units sold, has four doors and four wheels—a wash, right?
Wrong. Most cars have the same number of doors and tires—but wheels are a very different matter. After all, every car has a steering wheel. The gears that run your engine? Those are wheels, too. In fact, your car is full of wheels, big and small, that unquestionably outnumber the doors.
Even if we knock off the four main wheels and limit our count to steering wheels and transmissions, that’s an average of six wheels per car. Do the math, and we’re talking 8.676 billion wheels—more wheels than people, let alone doors for them to walk through!

Toy wheels

Toys are another major source of wheels, from Hot Wheels cars to LEGOs to Tonka trucks, Razor scooters, and that Fisher-Price corn popper toy that toddlers push around.
Hot Wheels alone has sold more than six billion cars, meaning there are roughly 24 billion tiny wheels out there in the world—and these miniatures don’t have working doors, meaning that every one of those wheels stays in the county. Hasbro’s Tonka has sold millions of pint-sized construction vehicles, with over 15 million sales of the iconic yellow Mighty Dump Truck alone. Hello, 60 million more wheels.
We could keep going—but adding up the sales of every single toy car company is a task too gargantuan even for us. Suffice it to say that if the gears-and-steering-wheel argument didn’t convince you, the toy industry produces enough wheels every second to outnumber the world’s doors without a sweat.

Bicycles and motorcycles

Sometimes two wheels are all you need—just ask bicycle and motorcycle enthusiasts!
Bicycles have been around since German inventor Karl von Drais patented the first in 1817, and there are about 1 billion bicycles in the world today. Motorcycles, on the other hand, were invented by Gottlieb Daimler in 1885, and there are just 49 million today.
Between bicycles and motorcycles, we add at least 2 billion wheels—and that’s not taking into account gears!

Other wheels: shopping carts, trailers, and furniture

Between cars, toys, and other wheeled vehicles, it’s already clear that wheels outnumber doors. But if you’re still not convinced, take a look around your home and neighborhood.
Got an office chair in your spare room (thank you, work-from-home)? That’s an average of five wheels. Shopping carts, hand trucks, trailers, and baby strollers all have wheels (and no doors). If you’ve got any furniture in your home with casters, those count as wheels too—and, if we’re getting really technical about it, every single sliding drawer in your home requires at least a couple of wheels to operate.

The bottom line

We’re nowhere near an exact estimate of the total number of wheels in the world, but it doesn’t matter. Already, we’ve identified well over a possible 37 billion wheels in the world—way more than the number of doors.

Which country has the most wheels?

So it’s official: there are more wheels than doors in the world. But which country has the most?
That honor might go to China, which has an estimated 302 million cars alone (not counting other wheel sources). However, itty-bitty San Marino might have the world’s highest concentration of wheels, with 1,263 vehicles per 1,000 people. The country that drives the least, on the other hand, is Bangladesh, with just 4 vehicles per 1,000 people.
In the United States, you’re probably expecting to find the highest concentration of wheels in L.A.—and you’d be close! Car ownership statistics show that nearby Murrieta actually has the highest rate of vehicle ownership of any US city.
The city that drives the least, on the other hand, is (of course) New York City, where the MTA runs all hours of the day to get New Yorkers around the five boroughs. But at the bottom of every New York City subway car, amongst the garbage and the rats, you’ll find eight glorious wheels.

Why it matters

Haters will say that the door vs. wheel debate is a pointless argument, designed to waste time and turn friends against each other. But there may be a deeper truth beneath the madness. Every wheel represents progress, forward motion, and power. If your first answer to the question “are there more doors or wheels” was “wheels, of course,” you may be more tuned in to those elements of life, more open to new experiences, and more driven to explore the world.
Wheels are everywhere—and that’s a beautiful thing.

6 Tips for Estate Planning and What You Need to Know

6 Tips for Estate Planning and What You Need to Know
Want create site? Find Free WordPress Themes and plugins.

Everyone has an estate, and so do you. Your estate is made up of everything you own, including your house, car, investments, life insurance, and furniture. It also includes your checking and savings accounts and personal belongings. But the thing is you cannot take your estate with you when you pass away.

 

When that occurs, you’ll need to decide how you want to distribute them to the people that matter to you the most. You must give instructions outlining who is to receive what from you and when they are to receive it.

 

But most people don’t realize how important estate planning is until it’s too late. According to a study by Cambridge Trust, less than 46% of Americans have a will. Then they’re scrambling to take care of issues that may last for years, if not forever.

 

There are plenty of things you can do to ensure that your estate is in excellent hands. And estate planning isn’t hard if you work with the right people, like estate planning lawyers. Find out what you need to know about estate planning and hiring the right professionals. This article will highlight some tips to help you get started with estate planning.

What is Estate Planning and Why Should You Have One?

Estate planning is making sure your family will have what they need after you die.

 

You might think you don’t need an estate plan, but you should write one, anyway. If you don’t, things could get messy. Your family may fight over your stuff, or they might give some of your stuff to people that you don’t want it to go to. An estate plan is like a map that tells people where to send all your stuff after you die.

 

If you don’t have any assets, you might say you don’t need one.

 

It’s critical to realize that inheritances include more than just money. Most likely, you hold objects that mean a lot to you even if they don’t have a “market value.” A family heirloom, for instance, has no monetary value, but it can have a lot of emotional value.

 

Without an estate plan, the government decides for you. When you die, the government takes your money and gives it to schools and hospitals. Your estate plan allows you to decide who gets what and excludes people you don’t like.

Who Needs an Estate Plan?

You don’t have to be old and rich to make a will. In fact, you should make one no matter what your age or how much money you have.

 

But estate planning should be a priority for unmarried couples and blended families. Without a will, assets go to blood relatives, so unmarried partners can’t inherit. Family members from past marriages and current spouses may or may not want to split assets.

Tips for Starting Your Estate Planning

It’s never a good idea to leave your affairs without a plan. No matter how unlikely it seems, it’s important to have a legal document that specifies who handles your finances after you’re gone.

Now that you have a clear idea of estate planning, you can begin with the following tips in mind:

  1. Seek Help from Estate Planning Lawyers

Many DIY estate planning websites, software, and trust kits say you can save money. But they are unlikely to produce a good plan that meets all your goals. Also, canned programs and forms do not provide the legal support necessary.

 

Putting it together is tricky without estate planning lawyers. Because only they know the rules on property rights, taxes, wills, probate, and trusts specific to your area.

 

If you live in California, there are a lot of estate planning lawyers in Fresno to get in touch with. You can talk to them about what you have, why you need a plan, and who should be in it.

 

Estate planning lawyers draft legally enforceable documents, so you don’t have to worry about it. It’s good to have someone help manage your assets, liabilities, and title arrangements.

 

An estate planning lawyer is important so that you can meet other goals. You may end up having to endure years of estate litigation if you do your own estate planning.

  1. Get Help from Family Law Lawyers for Guardianship of Your Dependents

How will you raise your kids if both parents die in an accident? Make sure you think about how your kids will get anything before you leave them. Unless you have a smart sibling, it’s best to put the money in a trust.

 

If you can’t resolve issues on your own, you need to seek the help of family law lawyers. The family law field covers everything from adoptions to probate. Custody, divorce, and probate overlap with the juvenile court for things like guardianships. So, family law lawyers can manage cases at any stage of the process.

 

To give you an idea, here are some lawyers you can get in touch with:

 

  • Divorce Lawyers
  • Child Custody Lawyers / Paternity Lawyers
  • Domestic Violence Victims Lawyers

 

But, before naming a guardian, make sure you consult with them ahead of time to get their consent. Also, keep in mind that they do not have to be the ones in charge of your child’s inheritance. A trustee can take care of your child’s inheritance until they’re old enough to do it themselves. Finally, make sure it is someone you can trust your children’s future once you’ve passed from an accident.

  1. Consider Disability and Death in Your Documents

Estate plans outline what you’d like to do with your assets and dependents. In case of incapacity or death, you need to prepare a few things. Without an estate plan, a judge in probate court can make such decisions for you. Protect your assets from probate by preparing estate planning documents.

 

Your assets and family status determine what you need in an estate plan. If you’re a business owner, you must have succession plans. Likewise, parents of special-needs kids should have special-needs trust. There are options for all income levels, no matter how you want your assets divided.

  1. Minimize Assets Lost to Taxes

Taxes play a big part in estate planning. The goal is to leave as much as possible to your heirs. This may be an issue if a large part of your estate is not in cash. This could imply selling assets such as a home or stocks you wish to leave to an heir.

That’s why understanding these taxes is so important.

 

  • Estate Tax
  • Inheritance Tax
  • Gift Tax

 

Get professional help if you have a large estate with many assets. Estate planning lawyers will help you draft a will that’s sure to distribute your assets the way you want.

 

In this scenario, finance lawyers can also help. Even ahead of time, you can help your beneficiaries avoid or limit inheritance taxes. They can work with tax professionals to find a way to reduce your estate tax bill.

  1. Merge Documents in a Secure Portal

When planning your estate, make sure your valuables are secure and accessible. This can include storing sensitive documents on secure file-sharing platforms. In case of incapacity or death, you can store your passwords in your internet accounts. Estate planning lawyers can help you organize and account for the relevant documents.

  1. Update As Needed with the Help of Modification Lawyers

You should change your estate plan every time your life changes. Re-evaluate it every three to five years. One reason is that you might have big events happening during that time. Getting married, having kids, and getting older are all good reasons to update it.

 

If you want to change a trust, a lawyer can look at it and change it so it will do just that. Of course, you can make modifications on your own. But, if you are hesitant about doing so, it is best to seek the help of modification lawyers.

To Wrap it Up

The best way to understand the process is to know what questions to ask and whom to ask them. This is why seeking estate planning lawyers is beneficial. You can ask them all the questions, get straight answers in layman’s terms, and make the best choice.

 

All in all, you probably have much more to gain from estate planning than you have to lose. What’s more, if you get a professionally drafted document, you can also draft your own letter with it. If you’re sick, this is a good way to let your family, friends, and loved ones know how you feel about them.

 

An estate plan isn’t just for the wealthy. It’s a planning process that needs to happen. There are ways to get legal help in this area; the internet can be a great place to start finding information. All you have to do is get started on making an estate plan before something happens that prompts you to do so.
