Overconfidence
I dont know what are the rules in this country, but if it were where Im from then the issues are:
1. That is a pedestrian crossing, you must get off your bycicle to go over it and have the right of way. Technically you cant even be there with the bycicle since that is a vehicle, but it looks like there is a bycicle road here. If not, double rule break.
2. There is a clear stop sign. The cars have the right of way and the cyclist must stop even if there is no traffic.
3. You must try everything to avoid an accident, even if you are right (he clearly isnt). Putting your hands up in the air, is clearly not trying to avoid the crash.
He around and found out.
Sorry for bad english.
