Buses can stop every other block, but in practice, they rarely do. Most bus routes that I've taken are neither full nor busy with passengers at every stop. Certainly not all day long. Most bus routes can get away with bypassing several miles' worth of stops at a time. Passengers tend to cluster around certain spots at certain times. Even the main routes have busy times, as well as quiet times in long stretches.
By building in the capability to stop very frequently, they can serve the most people and every area in the route, equally. But day to day, hour to hour, they are definintely bypassing stops, and I can name at least 3 bus routes where the vehicle will certainly reach the speed limit of 45mph or so in-between.
Depends on bus usage in your city. Mine is pretty high so it stops every stop. I’ve had bus trips that were 50 stops a leg and people are stopping at every one. That is a lot of delay right there. Doesn’t even get better at night; service pattern contracts then so ridership per bus is still high enough even at those hours. There ought to be more express service offerings that would skip over local stops.
