Hi
I maybe the exception but I prefer them as long as they are colour coded to car.
I believe they are door bumpers, in order to try to stop other car doors denting your car
Actually, on that note, I tend to park some way from where entrances are, such as supermarket. However, even though there are plenty of empty spaces, for some reason, it seems that everyone wants to park next to my car. Maybe it's just me or my imagination but that's how it's appears
I could be wrong though sorry
Many thanks
John
