Like others, my gauge cluster is good line-of-sight and I glance there often for peace of mind. (Sorta like using my mirrors while driving)
I'm also an "A4 Listener".
But the idea of an audible warning appeals to me as an added layer.
If nothing else, for the ignition/coil/EI protection factor.
Before I got the new MMI gauge panel with the cover, I was always concerned that a misplaced foot or knee would flip the ignition on, so I was constantly checking on it.
The cover has cured that worry.
Anyway, the alarm is on my wish list...
