You Don't Leave Space Between Cars

This morning while approaching an intersection the car in front of me drove past the stop sign and was partially into the intersection.  I noticed a car on the main road wanting to make a left turn.  As usual, I leave some space between my car and the car in front of me so if he has to, he can back up a little.  Well this guy was well into the intersection and started to back up; as I wanted to give him more room, I wanted to back up also.  Well, Mr. "Let Me Get As Close As Possible" was approximately one inch from my car; so, I couldn't back up.  It was all sorted out eventually and we were on our way -- finally.  The driver in front and the one in back of me were both stupid and/or ignorant for causing a needless problem.
It's important to always leave enough space so the front car can back up to behind the stop sign: where he should have stopped originally.  If the car in front of you is half way past the stop sign/red light white line then leave one-half a car length between your car and the one in front of you.  If you're the third, fourth, etc., car in back of the second car you should leave approximately one-half a car length between your car and the one in front of you.  Probably even more important to leave that space is if an emergency occurs.  That space will allow you to drive around the car in front and escape the danger.  Situations like these don't happen very often, but they do happen.  All cars in line are bumper to bumper waiting for the light to change.  An old car in the line catches on fire and you can't escape because your car is jammed in the line.  You jump out and see your car destroyed when the fire hits his gas tank and explodes.  The car in front of you rear-ends the one in front of him.  That driver gets out and starts shooting at the car directly in front of you.  As he's in front of the car in front of you and firing towards the rear puts you in the line of fire also, but you're jammed in . . . you're trying to crawl over the center console to escape out of the passenger-side door.  But a bullet killed your wife in the passenger seat, so now you're not only trying to crawl over the center console but also a corpse.  You see traffic stopped up ahead on the highway.  You slow down and drive to within inches of the car in front of you before you stop, of course, the car following parks his car inches from yours.  You then notice an exit just up ahead that would have allowed you to leave the highway, take a side street and get home without a hassle; but, you're jammed in so you sit there for a few hours.  Always leave room so you and/or the other driver can escape a bad situation.
