Damper for door hinges?
 

Most owners know that the door detents are not sturdy enough to hold the door open when you're parked at an angle. The doors will shut on you and make entry/exit hard, and loading things through the doors very cumbersome.

Is there any way we could mod in a damper system so the doors will shut more gently?

Subbing considering my fiance has nearly had her legs sliced off numerous times. Have to stop just before entering our angled driveway (and blocking traffic) so that the door is more easily openable
