Plus the SUV is usually point-to-point, leave home, go to work, come back. Whereas the bus is going back and forth ten times per day.

In Europe, the numbers differ even more. Lighter weight cars typically 1.5-2 tons, a new London bus can be upto 18 tons when loaded - that's ~5-16 units of wear for the car to 104,976 units for the bus...

But this is all supposing we're optimising for road wear, which isn't really the point of a bus system.

I'm old. Back in the olden days - the 1900s - 2-ton cars were not lightweight, the so-called heavy Chevys.
