These games are for entertainment only. There are things that you can do like drive into a curve at a high-rate speed and not peel out, flip over, break an axle, blow a tire, or a lot of other things you would need to worry about in real life.
If you gave some teens a chance they would drive just like how they see Mario drives. If it were up to me I wouldn't see a 16 year old being the wheel of a car they're just not mature enough for that kind of responsibility.
