It would have been good to demonstrate that in the video.

I find it common that people seem to think that a signal is good enough. They feel as long as they've signaled, they can go.

I often don't move until there's room for me to go and often, there's no need to signal.

I'll signal only if I need room to be made for me, and I don't go until the motorist has seen my signal and given me space to move.
