You Don't Leave Room for the Car Stopped at the Intersection to Back Up.

The vast majority of drivers do not stop at the white line at stop signs and traffic lights. They stop beyond the line and creep to the intersection. Many times into the intersection a few inches or more. Upon seeing a car approaching the driver may be concerned about an accident, or a large truck trying to turn left from the right and wants to back up. But, alas, you pulled up to within inches of his car so he can't back up. The fun part about this maneuver is that you now got him really scared that his front end will be hit or that the truck driver will get out and beat him up.
Which would be better:
1. Always leave 3+ feet between your car and the one in front of you at the intersection OR
2. Use your car to push his car further into the intersection.
