One pet peeve that gets to me is something that's done on a lot of commuter railways and S-Bahns, the 10/20 minute schedule. The schedule looks like:
2:10
2:20
2:40
2:50
3:10
etc, when it should be like this:
2:10
2:25
2:40
2:55
3:10
This minimizes waiting and allows for frequent service every 15 minutes.
What are your pet peeves?
Buses can be great. My guess is that you are dealing with buses that are either horrendously underfunded (low frequency, poor quality seats, stuck in traffic constantly), or are running transit services that should have been a subway many years ago. Buses can play a great role (especially trolleybuses) in cities that can't build or shouldn't build metro everywhere. High quality buses running every 5-10 minutes to every station can turn a single metro line into a comprehensive transit network.
The buses I deal wit run quite regularly, but during rush hour they just make traffic worse, and it wouldn't even be possible to run them every 5 min because of how busy it is heading in specific directions. If there were less cars, or even bus only lanes, I wouldn't be so against them though. It is a workable solution, but a street car is better in almost all situations a bus is used (and if the bus has to take a highway, train is better). But those too need a separated lane or else it makes traffic hell.
The real problem here is clearly cars though. I will bury my hatchet against the bus until after we have defeated the car. But then I'll be back on my anti-bus train.
