Any bus that has stops every 100-200 feet is unbearably slow. Even every 1/8 of a mile is too much to be an time efficient mode of transportation unless you have BRT imo.
As to unbearably slow, there’s this idea of express busses and buss only lanes etc. The core of cities really isn’t that big, it takes forever because traffic is slow or mass transit is infrequent.
Ideally you want a grid where bus lines are near intersections so going from North to East means crossing 1 street so you can go anywhere with 2 waits and a street crossing.
1/8th of a mile is every 660 feet, but the farthest you can be from one is the midpoint so 330 feet. However for every trip starting at the midpoint there’s another at and the bus stop thus the average would be 1/2 that distance again or 165 feet.
Assuming a 1D world, you can beat this in practice.
