"Ride to the left" isn't helpful when there's a bike lane, because you're already taking up a whole lane (the bike lane). It would defeat the whole purpose of having a bike lane if you had to take up a traffic lane to prevent people from right-hooking you. "Don't pass on the right" is only useful when traffic is going slower than bicycle speed (i.e. during rush hour when the streets are clogged, but not any other time).
