As a frequent LA bus rider, I agree that the biggest problem is simply the infrequency of service. I can deal with the ride being bumpy, or sitting next to crazy people on occasion. Even the slowness and frequent stops don't bother me. When you subtract time for parking, your trip takes not much longer than driving, especially when traffic is slow.

But 20 minutes between each bus during rush hour is just indefensible. It's not a viable transit system, it's just a last ditch option. When two buses get bunched together, now it's suddenly 40 minutes. Throw in a transfer and things can get ridiculous.

The Red Line train comes every 13 minutes but at least it actually comes when it says it will (most of the time). The bus is scheduled to come every 15-20 but in practice it's more like two come five minutes apart and then you wait 25-30 for the next one.
