My first Touareg had it and it worked like you'd expect, stop at a junction couple of seconds later it stops.
New car now cuts as your coasting to a junction at 2-3 mph. I went back to the dealer, no seriously I did think they'd listen, they didn't. Told them it was dangerous, I mean if the engine is OFF surely so is the power steering and power brakes. Oh you've got electronic power steering, err no I don't it's hydraulic! Anyway it only works when it feels like it and that isn't to often so when it does work I turn it off as it's just a flippin pain.
