Seems to be enabled on certain Audis..I've followed a few now that do this (Q5, A4 and possibly an A3). Bit of a rare sight though..
...an Audi using its indicators
What? Your confusing Audis for BMWs! I drive an S4 but I don't claim to be a proper Audi driver - ie I don't deliberately force my way through in risky situations - but I do agree that most proper Audi drivers do, I see more of that when driving my wife's Polo!
Also, quite a few newer trucks and buses now have dynamic indicators, which, I believe, is not exactly the way that the UK transport rules outline that they should operate, but I suppose no one will get stopped as its only UK that is dragging its nationalistic feet over bothering to make changes to regs.
Actually I and others find that not bothering to use indicators can be a regional thing, I live near Edinburgh and it seems most "savvy" motorists near Edinburgh know where they are going - so no indicators get used!!
Edit:- oh, my bad, that was a very late response to that posting, very very very late!!
