Reminds me of almost getting hit by a car last week while cycling to a shop, the guy only looked left and not right when I was approaching, just when I was in front of him he started accelerating until he saw me and pushed the breaks.
Or maybe this morning when there was no bike lane and I had to take a left turn some idiot just stopped his car in front of me, he clearly could see that even if I didn't take a left turn the bike lane was blocked (yet again).
And let's expand this a bit, bike lanes in my neighbourhood are shit.
Holes here and there which make it very dangerous for me, but hey atleast the government doesn't give a shit about repairing the road for the cars.
And truck drivers and their trailers... man they have to block everything don't they? Making you take a whole detour when the driver could just move the damn thing a bit, the engine was running and he was in there too!
Basically: Motorvehicle drivers just don't give a crap about cyclists.

Basically, I don't see a problem with cyclists riding their bicycle in front of your car.
You should have some patience, unless the cyclist is really an asshole when he drives in the middle of the street instead of the side of the road and unnecessarily obscures every car's path, then you have all the rights to be irritated.
