Who invented the first car and in what year?

It really depends on what you mean by the "first car". The first thing that people would recognize as being car like was invented by Karl Benz at he end.of the 19th century. It had 4 wheels, some kind of brakes, an internal combustion engine with a whopping 1 cylinder that drove the rear wheels via a chain amd sprocket. The steering system is what makes anyone looking at his thing go "what" because it's a tiller style steering arrangement, which is an armature ending a joystick like deal that you move side to side to accomplish the same thing that turning your steering wheel does. This thing was really.nothing more than a wooden wagon with some handmade internal combustion bits bolted to it. That said a few decades later we'd get the model t from Ford which basically ushered in the age of personal transport via car. And a T from the 1920s does look like a car but if you ever see one in person you'll notice all the extra stuff the driver has to do, like manually adjust spark advance, air fuel ratiOS, hand prime the carburetor or carburetors depending on the setup, there's no starter motor so you have to hand crank the engine etc etc... And back then there wasn't a standard for what gasoline should be made of, or where it should be sold so most early cars like the T were multi fuel. A T could run on the weak sauce 40 or 50 octane gasoline or you could shoot over to your local pharmacy and buy a couple gallons of turpentine to run your tin lizzy. Anyway the model t was tally the first car that reached everyone, before the T cars were one off handmade toys for the rich, they were extremely unreliable and inferior to the horse they were attempting to replace, and it wasn't until Ford came along and solved the price, standardization, and overall dead simple long lasting mechanical bits and a layout for the car that we still have today.
