Today I was waiting for traffic to clear so I could make a left hand turn. I was positioned in the leftmost part of the lane so cars behind me could get by. Another biker came up on my right hand side and stopped to make the same left hand turn. I thought it was a bit odd as now he had put us both at risk of getting hit by traffic behind us. I could see if we where riding in a big group. He turned a second after I started so we where basicaly side by side making the turn. Was he doing it right? Or should he have waited behind me for his turn. I dont normally ride with other bikers but sometimes its unavoidable.
