the thing that has been pissing me off lately are folks that seem to have not the slightest idea on how to navigate a 4 way stop. They are afraid to go, they sit there till all the other cars are gone. Happened a couple of times in the last month.
They've redone the parking lines at the pool I go to. They have made it much more efficient. It's mostly slanted parking, with 2 parallel spots where it makes perfect sense. The angle of the slanted parking was increased, so now, when you go to leave, you can just put your car in reverse and you will automatically be a the perfect angle to back out of this limited space, narrow parking lot, and onto the street.
But, of course that would be too easy. I see (actually mostly men) try to back out, then try to manuever about 500 k-turns in this narrow little space to turn themselves around to drive out frontways. Damndest thing. And, people try to slant park in the parallel spots.
