What are you pet peeves whilst driving on the road?

I think almost everyone identified tailgaters as one of the main problem. 

Thankfully, with a 4x4, the likelihood of this happening is rather low but I still get some from bigger SUVs. 

However, as Barry had pointed out, I have witnessed a fair number of smaller cars being tailgated by taxis, sedans and SUVs of various sizes.

I am having a small car and SUV both. I am hardly getting any tailgating. Key is i am always driving on the speed limit, which makes me most of the time fastest one on the road and i am leaving the left line empty as much as possible. Cars i am seeing tailgated are driving on the 2th lane 90km at 120km road. Or on the left lane 100-110km on 120km road. They are thinking they are fast enough. There are freaking 6-7 lanes on the road they are acting like there is only 2 lane available. Most of these people are not moving right unless you get really close to them, even right lane is totally empty!. If you keep distance with them they are thinking you are alright behind them.
