I think it is a splendid Idea, actually - why not have those in the HOV lanes here, too ? It would damned sure cut down on the amount of illegal traffic ! If that is a lane specifically for busses, then the cars shouldn't be in there - and also, IMO - stupid people shouldn't breed, either - sorry for the innocent child, but had the parents been smart enough to follow the signs, and not drive in a bus lane, then that would have never happened ! I say, bring it on - I would LOVE to see that implemented in America - of course one idiot is all it would take to sue - just like the McDonalds lawsuit and the hot coffee. Why not invent something that stops lawsuits ?
