As a rider, the trolleys are my least favorite vehicles. In theory, electric is great, lots of torque, whatever. In practice, they're the slowest vehicles in MUNI's diverse fleet. Go too fast, and the trolley pole comes off the wire, and the driver has to walk back and reconnect it. Get stuck behind a slow driver, and you have a whole pile of buses moving glacially. My least favorite time was when I had to use either the 14 or the 49, depending on the destination, because they share a lot of the same route.

The diesels work just fine on first or second gear, and the steepest hills with buses are diesel. I find especially amusing how the 29 scrapes the ground when it moves on and off from Excelsior Heights. The very steepest hills with public transportation have cable cars, obviously.
