How to prevent car door scratches?

Question

idiots park close to your car, and open their doors wide and hit the side of your car, and it leaves that little white scratch or something, how do we stop that or prevent it?

Answer 1

Take your doors off and put them on the roof rack.

It worked for me.

Of course, you could also pimp your ride LoL.

Answer 2

never go anywhere? Seriously, there's really not much you can do about it besides try and park in the least populated part of the parking lot.  

Answer 3

Park at the back of the lot away from everyone else and walk!
