The biggest thing I see with this is you're now blocking both left and right turns while the vehicle is moving.

If you look at something like the 511 Spadina Streetcar in Toronto which runs on a right of way (ROW). You're in one of three states: the alternate direction of traffic is allowed to move, traffic going straight is allowed to move (including the streetcar), or cars are taking left turns.

Other LRTs and Streetcars either run on a ROW or they are on their own road without other modes of transit. Similar to portions of the Nice trams, and dozens of others.

LRTs and streetcars are generally running in the middle of the lane meaning that will only block left turns. But if you have a tram (they call it a bus, but that's stupid) that's required to be on the outside of traffic it would have to stop or slow down whenever a car is turning right. And when cars are taking a right turn, if there's not space on the road due to a back up, that tram will now be forced to stop since the car will be on top of the tracks.

Given the cost of building the infrastructure vs the time saved. I don't see how you're coming out any better than an LRT or BRT.

This is if it's in local traffic. I think a lot of these issues could be avoided on highways if you're able to fiddle with the design of off-ramps. Of course, that highway would need to be two lanes in each direction.

Yeah while it passes you can't turn left. Assuming there's only two lanes in each direction. But only while it passes :)

In terms of beating BRT, I guess it avoids the requirement of a busway?
