A poor workman blames his tools!
I've just bought a Chev Uplander van, which has electronic traction control, and we just had 8 inches of snow here. I thought at first it might be a bit gimmicky and kinda useless, but it has proven to work perfectly, and I'm glad I have it.
It works by pumping the brake a zillion times a second on the slipping wheel - no screwing around with the differential - and flashes a message on the computer display to tell me what's making that odd noise.
If it screws up the bad drivers, tough shit! They'd find some other reason to have their crash anyway, so don't go blaming the traction control mechanism just because your vehicle supplier couldn't get the engineering right.
