I don't think I have lack of respect because I have given up either.
I still don't rest or hit my car door against other peoples even is its a pile of crap.
The one thing that really, really, really, really does get my goat? Wealthy people in 4x4's who just scream into the car park in £100k+ motors park in 2 spaces or at an angle next to another car, get out and just wallop your car with their door with their nose in the air of superiority!
That is real lack of respect because manners and respect do not cost a penny.
I really have to hold myself back in those situations.
Best just to leave it as the world has a way of correcting things like that, Karma! What goes around comes around.
