Bus rapid transit can actually be really nice. You know that rock stars and politicians practically live on buses while they do traveling events? Of course a BRT isn't going to be that private luxury, but even a middle quality charter bus that makes limited stops is pretty darn good. Having dedicated lanes removed the worst part of buses compared to trains.
I used to daily take the AC Transit transbay buses from the East Bay to San Francisco, which are double-decker Greyhounds and have comfortable reclining seating with tables and wifi. The single entrance/exit is a benefit, because it only runs commuter hours and so in the morning it only picks up in the East Bay and drops off in SF. It allows enforcement of fares too. It's a higher fare, but that also attracts a commuter clientele. The main problem with it is that it is too popular and gets crowded, and you're SOL if all the buses are already full at your stop. But that if the flaw is that it is too popular, that's the best and easiest problem to have. Sometimes a regular AC Transit bus would show up and we would all groan and curse.
