Buses carry many more people, so the damage-per-user-mile is mitigated.
Also, buses don’t require storage at the destination, aka parking. Cutting parking space allows the city to be more walkable, further mitigating vehicle damage.
And increased density is also good for the tax revenue per square mile, which is also good for the city’s bottom line.
still a massive win considering that the F-150 is the top selling vehicle in the US. Not car, not truck, overall vehicle. A few dozen people in big trucks will far outweigh the damage of a bus
