I HATE THOSE!!!!!!
hatchback owners: does anyone know what this plastic shit is and if i can take it off? (back doors. and yeah, i know i gotta wash my car)
I have them too, but I don't have the courage to try and remove them.
The only reason I can think they are there is if the door got out of alignment and hits the edge while it closes. But you would have more to worry about than chipped paint if the door is miss aligned.
