Interesting take. Where I live (The Hague, Netherlands), trams are slowly turning into light rail systems. Where trams historically shared the roads with cars, they are now increasingly running on separate tracks (elevated or otherwise). This allows for different kinds of (more comfortable) trains, because they do not need to be built for collisions with cars.
