On my long commute I go through this junction. There are two lanes, approaching a traffic light with an ASL. I want to go straight on. The left hand lane is a bus and cycle lane for a long way back, but near the junction it becomes a left-turn lane as you can see at the point I have linked to. I usually come down the left hand lane, as,at the time I am there there, is usually a long queue of traffic in the right-hand lane going straight on. Twice I've had people pull into that left hand lane in front of me, and I'm concerned that at some point someone is going to pull left into me without seeing me. The options that I can see are 1) sit in the queue of traffic 2) keep using the left hand lane but go very slowly and keep an eye out for people pulling left 3) filter on the right (something I am a bit nervous about trying) Suggestions?
