Bingo. I'm pretty sure RLCs are illegal in South Dakota (not sure where exactly to look, but a google search seems to corroborate the theory), but in my town....there'd be an outcry if they tried to install them, at least during the winter.
I drive a 2003 Mustang. Rear wheel drive, not particularly heavy. Even with 250 extra pounds of icemelt bags in the trunk, it takes me an extra 5-10 seconds of feathering the gas to get moving on icy roads, and I have to start slowing down about 50 feet earlier than when it's dry.
Add to this that, during the winter, only the 4 or 5 major artery roads are ever satisfactorily cleared (and not due to plows, but due to the amount of traffic they get), sand is rarely re-applied to the intersections once it gets swept away by traffic, and it takes the city about 3 days after it stops snowing to actually start clearing the snow out in the first place.
Anyway, this morning's short drive to work is a perfect example. It was 31F yesterday - surprisingly warm, enough so that some of the snow and ice melted in the sun. Then it dropped back to 0F overnight, freezing the wet roads. This morning we had a thin-but-troublesome layer of ice pretty much everywhere. If I was less than 50 feet out of an intersection, even going slow, and the light turned yellow....if I hit the brakes, I'd end up in the middle of the cross street. Red light cameras here would wreak havoc on people who can't help that they can't stop in time.
