Nice one! That's why its compulsory in Holland to signal with your either hand which direction you're turning into well before time to avoid this kind of accident or possible disputes after somebody dies. I guess we can guess who that'd be. :P

Thus the importance of having own cycling path so motorist are more aware before making turns giving cyclists priority. I'll post you some video of the practiced norms when I can find the time. You'd be spoilt biking here man.

That cop car didn't even signal right before the right turn.
