Just have some bleeper which gets more and more urgent and if the
computer thinks the bus is going to strike the bridge then it slams
on the breaks. The technology exists to do it.

"just" Hmm... Given that many bridges have very little clearance under
them, how will this device tell from sufficiently far away whether the
bridge is six inches too low, or six inches higher than required?

Because it has a GPS and a gazetteer of low bridges?

iBus does *exactly* that.... So we should see an end to this sort of
thing in London.
