I'm gonna bet that worldwide more buses have toppled over in the
last 12 months than trams in the last ten years...

While still on the road (remember, leaving the road and hitting a
kerb/barrier doesn't count).

And why is that, pray tell?

The activity being measured is over-speed causing the vehicle (bus or
tram) to topple over. A lot of the KSI in such a situation is caused by
the scraping of the broken windows on the ground/tracks.

I presume this means the Croydon tram incident
doesn't count either, since it left the rails

toppled

and hit an OLE support...

Having slid on its side.

And what's the ratio of installed base of buses vs trams.

I'm terms of investment to protect the most people, that's irrelevant -
solving the problem of buses rolling will save many more people than
solving the problem of trams rolling.

Not if the investment has to be implemented on 1000x times as many
vehicles.

In any event, we are still a little short of reports of buses which
toppled over sideways *while on the road" and taking a curve too fast.

Vehicles leaving the road for a number of reasons, then eventually
hitting some obstacle which unusually toppled them over, will have a
different injury profile. Especially the ones that didn't end up
rolling.
