I'm worried about being on the road with these. If they are as indestructable as suggested/demonstrated, it seems like everyone else on the road becomes the crumple zone for both vehicles. Perhaps the anti-dent is different from crumple zone considerations, but definitely a bit intimidating to share the road with.
I'm guessing the crumple zone on this is going to be better than a vehicle with an internal combustion engine! That and the fact that semis are everywhere. This being on the road doesn't worry me in the slightest given the other vehicles already out there.
And does it only come in one color (stainless)?
