EVERYONE speeds. Why? Because most highway speed limits are unreasonably low for the conditions and design of the road.

Exactly. But why are the highway limits unreasonably low for the conditions and design of the road? Because everyone speeds.

Therefore, we must assume, that if nobody speeds anymore, we can actually increase the speed limit. Furthermore, because most speed limits are designed for wet conditions, we could hope, that the speed limit will be even more increased on dry days -- that would be easy to do!

I want this system!
