Thats probably more to do with the side wheels on the bogies the
rubber tyred systems have. I should imagine derailing such a setup is
almost impossible unless the train actually rolls over.

Probably, yes, but those *are* the two reasons why the rubber-tyred
system was chosen for Montreal (where there would never be any traction
problems for the rubber tyres in wet weather, because the entire system
is underground. There isn't even any open-air access to the depots,
because the system is designed to remain unaffected by Montreal's very
severe winter weather).
