I try to avoid carparks at all cost, I've had too many door bangs-people just don't care!! If I have to use a side by side park i will take two spaces.
usually i try to park on side of the road, (front to back), people here seem to be more careful parking than opening doors, if they can't get in they go elsewhere, finding a park is not usually a problem here.
My front bar is a reasonable height but I am still cautious over bumps..as it has scraped 1 driveway before.
and Yes I have parked in a small spot just to change my mind and move to a bigger one..lol
I also try to avoid parking under trees, or behind my brother....he backed into me in the driveway!!
