We have seatbelts, air bags, ABS, traction control, traffic control devices, traffic calming devices, speed limits - and yet people still crash. Driver training won't stop people from crashing.

People are still going to crash no matter how much salt you dump on the road. When you salt the roads, people just crash at higher speeds!

Zero salt = plenty more crashes. I've lived it. You do not want to see it.
Way too much salt = environmental disaster (and cars rust out very quickly, to boot). I've also lived this. You do not want to see it.
There is a happy medium, eh? Of course people are going to crash, but that doesn't mean we should just give up and never use salt. I haven't seen any hard figures one way or the other, but Calgary seems to use a lot less salt than many jurisdictions. I think we're on the right track balancing safety vs the environment.
