Why can't people exit/enter a car properly?

OMFG! :banghead:banghead:banghead:banghead My doors have springs in them that pretty much close them for you, you just need to gently start it moving and itll shut, FUCKEN EVERYONE just slams my doors SO hard. GYAD! I hate that shit, what am in ina Benz or something?(the joke im mkaing here is that a lot of their cars NEED to have the doors slammed, if you didnt know).
