Personally I think if anything, it would be marginally safer. The sudden change from bright white light to amber would catch your attention, causing you to focus on the car that just put it's signal on instead of all the cars around it. I notice it especially at dusk - I seem to look at the car only because of that sudden change in light brightness/colour.
The only time I can see it actually being beneficial is when you are about to make a right hand turn from a driveway onto a major road and the Audi is changing from left to right lanes immediately before the driveway you happen to be turning out of, and MAYBE the DRL thing will help you see the signal more clearly lol
Most other scenarios, you will be going in the opposite direction of the Audi when it's signal is put on... so... I don't see any other point, other than another almost useless feature. Besides, it's not that Audi was the first manufacturer to do so - I have seen many chryslers with this feature (mid-2000's mini-vans, etc).
