It's very scary when you lose control of a bus - even though they've got ABS - Traction Control, etc (No sport mode unfortunately).And there is really no reason why you should lose control of a bus, unless the laws of nature take over, in which case your judgement was wrong. In other words, if you ain't sure - don't do it!
Can you imagine the damage an out of control bus could cause?
And that's just with me at the wheel - imagine nearly 40ft of bus starting to slide on its own.
They are quite reliable in snow, mainly because engine weight is over rear wheels (four tyres at rear driving), I have not been stuck yet.
Famous last words.....
