If you cycle regularly though, you’re probably more prepared to deal with the push and pulls from the air of a large vehicle passing (which they can still surely feel, even if they don’t have to deal with maintaining their balance) and better at maintaining your line. Someone who just never cycles would probably have a lot harder time dealing with both of those so the bus would need to pass further away to make it equivalent, but then you wouldn’t really get that effect of having a wall right next to them. Either way is missing part of the experience.
