I think it's partly the same situation as with ABS cars. Drivers forget they can steer while braking to the max.. Many times they will jam on the brakes and drive right into an obstacle. I've crashed hard when I locked a rear wheel, I now have ABS and wouldn't go back. The GW is not the best bike to argue the benefit of ABS as it is pretty hard to lock the wheels. Try a lighter bike with/without ABS and the benefit becomes more obvious. You only may need it once, but then you'll appreciate it.
