If you want to travel the world then you need to know how to drive since that is almost a prerequisite. There are no one that would stop you, but you need to drive a car to get to where you want to do. Honestly, when you are on another country, you would want to explore it, but you won't get a free ride. You would need to hire a car and drive it by yourself since most countries don't accept other driver. So, if you want to get somewhere then you need to know how to drive. Driving is not a rocket science, but you need to be careful while driving because you might get an accident if you are not careful enough. The idea here is to park your car as fast as you can since you would need to do it twice or more depending on the level. After, you have done that then you would be free to get out of there and go on to another level. Don't think that this would be easy since there would be other car that runs around within the area and you don't want to collide with that.
