Are those humps really necessary? They slow everything down but to an absolute crawl at time, they could be maybe a little lower or maybe longer, but not as high. Anything above 3mph your car just jerks up like you have a hit a ramp at 60mph
I always drive round the to the back since I always have, I once parked on the way in, in the first space I got to, wont make that mistake again!! Took forever to reverse out. No-one was kind enough to let me out either.
On a side note, this is possibly one of the best smilies I have ever seen on an internet forum.
