Maybe you could use the 'magic sponge' effect and create a safe zone around whatever car you drive? That way, whatever you may have hit will be absorbed by the sponge. Of course, the sponge will be invisible so as not to spoil the look of your car
Here's one I fitted to mine:
As you can see, it doesn't spoil the appearance at all and it came with a remote to remove the 'cloaking' effect so you can see where to unzip it and get in/out.
Cheers
