There's more to do when driving a bus, therefore drivers don't fall

over because they took a bend too fast.

It certainly does happen. Indeed, it's happened a lot more with double
decker buses/coaches than it has from trams (once).

Indeed - a quick search for coach overturned on google returns a
considerable number of examples. Some where the driver had also fallen
asleep...
