It does. Because junctions still slow them down, as do groups of 30 tourists all getting on at once, asking questions about whether this bus goes to the castle.
You can tell exactly where you live based on the castle reference. Happened to me once when a tourist in front asked about the castle and I couldn’t quite believe it was real.
This is also mostly fixable, with signal priority. Except at complex intersections where different roads each have transit lines fighting for priority.
And the easiest solution to reduce the use of cars?
WFH. Every company implementing a RTO politic should be declined next time they try to get certified for some green-washing label. Especially when some government grants are tied to those certifications.
