Some of those... I get the urge to grab a bat and just bash their skulls in. There are so many people that just shouldn't be allowed to ever get near the driver seat. I see almost every day people that zig-zag between lanes over no-cross-lines at insane speeds, people driving into roundabouts without looking, people driving in the middle of two lanes while messing with their car stereos, people suddenly turning without using the signals etc. etc. etc.. And I've shouted "meathead" to plenty of cyclists suddenly crossing a road even though the light is green for cars... And most recently I was almost hit by a car coming from the left (people seem to have forgotten the rule to let traffic from the right go first).
Still, it's funny to watch as long as you're not a victim of these buttheads, esp. morons who drive too fast and crash/run off the road and hurt only their own cars.. that creates a sadistic pleasure to watch.
