On: Removing street signs, lights and arrows increases...

That's a really good question. I think I should, but I find the concept somewhat disconcerting.

There are a fairly large number of single vehicle accidents so I don't think that it really would lead to a measurable decrease though.

Alternatives: everybody should drive cars with bodies made of hardened but very thin glass (I'd support that one).
