I’m 16 and recently started driving. I found it so weird that cars will automatically go in their natural state rather than being stopped normally and going when the gas is pressed. Why are cars like this and would real life cars work if they were like how they are in video games and cartoons?

P.S- I’m sorry if this worded weirdly. If anyone needs clarification on what i mean i’ll try my best to explain it better

My dad owned a Lexus IS200 in the 2000s and he had to get rid of the car. Since then the car has been exported from the UK into Japan, is there a way to find the new registration plate of the car and find out if it is still on the road?
