Every city I’ve ever visited or lived in that has trams, mixes them with normal road traffic. Zurich, Karlsruhe, Heidelberg, Nantes to name a small number. I wonder what the problem is with folk in the UK who can’t cope with the idea.
I would suggest it's a few things
Years ago when we had trams everyone was used to them as they are in many of the cities that have them now
The standard of driving in the UK has plummeted people don't know how to interact with other vehicles and enter and leave junctions and roundabouts.
Cyclists get a away with murder in the UK compared to overseas cities.
My experience driving overseas is that yes there are stricter rules on the roads concerning cyclists but the cyclist is expected to obey them also.
Here there are people swerving in and out of traffic, riding down the side of people trying to turn left riding through red lights
Little wonder they get clipped by cars trams and trucks
