I'm sure poor track condition probably had a lot to do with it. With respect to reliability, I think buses and even trolley-buses have an advantage over streetcars in traffic because they can go around obstructions in the street, while streetcars really can't. Trolley-buses have to stay on roads with overhead lines of course, but they still have more lateral freedom than trolleys on rails.
