The Zeds dash lights up whether the lights are on or not, stupid in my opinion. I was caught out a couple of times when I first got it and both times were in built up, very well lit areas, so I wasnt able to see that they weren't on. My stupid fault of course, but if he dash lights weren't on then it 100% wouldn't have happened.
Anyway, my pet peeve is drivers in the left lane entering a roundabout and following right round to exit after 6 o'clock. It happens a lot where I am because there are 8 roundabouts on a dual carriageway and I've lost count the amount of times I've seen someone nearly lose their front end because of these idiots.
