The problem is that it's mostly useless because it shows up at random times regardless of what lines are on the road! Maybe it's programmed for UK roads and the lines are different? I've been to the UK, but I can't remember what the lines are like. ;-)
Yes it is quite annoying because I don't know when it would pop up.
Since the British drives on the left side of the road, the lane change cameras might be picking up a solid or double set of lines indicating do not pass to the right ?
I know that you can not pass on one side in Europe especially on the motorways. Something we wild westerners in the US don't abide by - quite dangerous when you can pass on either side when on the freeways.....
Or when I was in the UK many times, I would see those zig zag lines in the city streets where you don't want to change lanes for pedestrian safety ???
