In no particular order:
People not signalling, especially when you've stopped behind them at lights, thinking they're going straight.. but actually they were turning and just didn't bother to let you know.

Slow drivers in the fast lane, yeah. That often causes the next one - pushy drivers tailgating. Though I can understand, sometimes.. sometimes I'm the 'slow' one (usually the person behind is speeding, not that I care), and there's not much room in the slow lane to move over.. so I'm not sure what the best move is..

People talking on phones is a biggie. It's illegal to hold a phone and talk on it, here; though it's legal to talk on handsfree. Nevertheless, I think studies have shown that it's the cognitive load, and not the lack of a hand, that has the biggest effect.

And, one of my biggest annoyances - cyclists who disobey traffic rules, especially riding through red lights, etc. If they want people to respect them as equal users of the roads, then obey the rules like everyone else. Cyclists who disobey road rules do the obedient ones a disservice. They also make me want to run them over. I've been able to restrain myself.. so far.
