I consider myself to have a kind and considerate disposition when I'm driving. I let people out when I can and even feel guilty if I don't. I don't tail gate and rarely use my horn at all.
That being said, I get frustrated by people driving without due care and attention. Why sit in the middle lane when the left is empty? Why are you not able to control your speed so you're not going from 60 to 80 all the time? Why is lane discipline an alien concept? Do you have a rope attached to my rear bumper is that why you're so close?
Pretty standard items but I've closed the door on people undertaking me before now and they've subsequently tried to drive me off the road. I've only ever had one confrontation which has led to me stopping which ended pretty quick when the other guy realised he was facing 110kg plus of PI55ED off power lifter/Prop. This was at traffic lights and my wife had stalled the car, he got out and started shouting, I got out and he got back in his car.
People seem to get this metal box around them and they forget to be human beings. We all make mistakes and you get ar5eholes in all walks of life, how you react comes down to control of your temper.
That being said, people do seem to aim for BMW drivers. I used to get cut up less and let out of junctions more in my Honda. The other day, I had the roof down, tunes up and was enjoying the sunshine when the guy next to me started making the 'w4nker' gesture at me. I concede the point, I'd have thought the same thing on seeing me. However, I didn't give a toss as the sun was out, I had some tunes on that make me want to scream in happiness and I was driving a car which gives me more smiles per mile than miles per gallon.
Overall, bo11ocks to them all, I love my Z.
