There is one terrible issue I encounter almost every time I ride to work. In the mornings the traffic is stopped all the way to work. The stopped cars leave gaps next to the side roads so cars coning from the other direction can turn across to reach them. Because there is a wall of cars in between the bike lane and the other side of the road, neither the turning car or I can each each other so the car blindly turns across the road assuming no bikes are coming.
