I always mesh in with traffic at intersections even if there is a bike lane. I feel safer doing that. I know that I won't be hooked too or having a car not seeing me behind someone and turning into me. Plus, normally I go through just as fast as any car. If it is a red stoplight with a bike lane I go up to the front and mesh in behind the 1st car in line. To me at stops a bike has the same rights as a Car or motorcycle.
