Such devices may offer value for money on trams but not on the road (eg
because the current technology means they are easier to make work on
rail than on road). But it'd be nice to have evidence that are
recommended because they offer value money and not just because they
would have avoided one incident. And, as Recliner intimated, there
are rather a lot of trams operating elsewhere so the evidence might be
expected to include the use - or absence of use - of such devices
elsewhere.

I think it fundamentally raises the question - is a tram a bus on
rails, or a train on the road?

If we see it as the latter, up go costs, which means more people in
actual buses which have none of these standards.
