So, I'm not the previous commenter, and I'm not about to suggest we should ban cars outright (there are quite obviously situations where cars are needed... I mean, anyone who lives in an isolated place literally has no better option)... That said, I would love to see cities free of cars entirely.

Buses are more damaging to roads, yes (although I'm confident that your 10,000 number is hyperbole, I found a source which suggested than an empty bus does ~170 times the damage of an SUV, or 1,700 times the damage of a compact), even per passenger - which is surprising. But the benefits are quite significant in other regards - energy, pollution, road space, safety, etc. Plus, you can in fact design busses which are less damaging to roads by giving them more wheels!

Road damage is a relatively small part of why people like me want to see cars be (where practical) a thing of the past. There is a place for busses in that world, alongside other less damaging forms of transit - especially bikes and trams within cities where busses would be the competition. Certain routes are too far for a bike to be practical and too sparse to warrant a tram, so busses make sense in that case.
