No..I don't agree. Much as it's extremely annoying , they're no damaging anyones else car so it would be criminal to do it to them...
In Spain last time I was there.. I had sold my car some time before so we got a hire car.
I parked in a bay on the street where the bays were slanted...there was 4 cars , 3 were parked straight on instead of at an angle, I parked at an angle realising that my rear would be sticking out onto another bay if I parked illegally..aka straight on....
I was gone a very short time.. in that time, someone had keyed my car and left an irate note in Spanish telling me to learn how to park!
but 3 people had parked like this...
