Visual Aids for Cycle Training

The cyclists proceeding along the bus lane do have priority over turning traffic, but you learn quickly to cede priority in bus lanes. Rolling through after eye-contact is no guarantee that a vehicle will not swipe you. In the same situation, I'd wait again.

Yes, the rider behind (who makes the hand gesture) was not watching how the situation was developing ahead of him and nearly rear-ended me. I sometimes shout "slowing" in these circumstances (or use club hand gestures if there's a somebody drafting) but the guy was not even close when I looked back before the junction.

There's no guarantees that you won't ever be hit in any circumstance, but stopping and giving way to drivers in this scenario sends them (and those cycling around you) mixed messages - what if it's not you they meet next time and they turn across a rider who was understandably expecting the right of way?

I don't think your video is showing best practice in this case.

Happy to be corrected by those with better knowledge of the National Cycling Standard. Slowing to confirm safety (eye contact) and then proceeding with right of way is what i'd teach.
