Exact reason i drive a toyota land cruiser, i figure id rather have the guilt of someone i don't know dying in an accident with me than myself or family dying. IMO bigger is better on the road.
I'd kill for an FJ40 Landcruiser (the 70's landcruisers)... On the other hand bigger isn't always better on the road. Just look at the Ford/Firestone roll over scandal.
That said, you wouldn't catch me dead in a dumb car, I mean smart car.
