This is really easy to handle. For one recent example look at the US 1 BRT in Alexandria, VA. The buses run in separated lanes in the center; cars can make left turns at several intersections with protected left-turn signals [[that is, when the left-turn light is red, it's solid red not blinking red) and there is a bus signal for the buses to go through when safe; equipment on the buses turns the signal green for the bus when necessary.

None of what is proposed here is new or technically difficult. It just costs money to do it correctly.
