I'm designing a 3d model of a car with some specifications.
The question that I thought of now and also is a good question as I don't personally know the answer while driving my own car is:
How can you not hit the car in front and also behind you?
For example, how do you know when you're too close to the car in front(while driving forwards) and also the car behind(while reversing)? are there any reference points, etc?
