Irelephant.
The "damage to other cars" bit, that is.

If parents cannot teach their children to open car doors slowly and carefully, so as to avoid damaging other people's property, they shouldn't be allowed them.

My irrational hatred is other people's children. Can you tell?

I agree, kids who cause damage by flinging doors open deserve all the beatings they get...
but that's not to say that I don't approve of the spaces. Until you're a parent you'll never understand the frustration of having to lug around a carry cot which you struggle to get out of the car because some twunt in a two-seater sports car has decided that the nice big space closest to the shop is reserved especially for them.

My little fella is 18 months old now, can kind of walk, so I don't use the spaces any more. Ever since I got into a heated argument in the middle of ASDA with some stuck up bitch who decided her 10 year old daughter was too retarded to open doors properly used it as an excuse to pinch the space I'd been waiting for, I vowed never to do the same to another parent.

BTW, her daughter showed no visible signs of being retarded, I'm guessing it was just fuckwitted parenting.

I would say
Using a parent and child space when your child is 18 months old, and can barely walk, is completely reasonable. Check out my profile and the story about complaining, it may give you a chuckle or two.
