Yep, mine pops up AFTER I shift back out of the drive and shift into drive - basically force me to either dismiss the alert by taking my eyes off the road or immediately stop my car (to dismiss the alert) and possibly get rear ended. We really should complain to NTSB or someone and have GM do a 'recall' for this 'feature'.Yes mine also pops up sometimes after the car is moving. Also of course the fwd-looking camera takes over the screen as you pull away from being parked. Which means you can't get at some functions until you're going fast enough to lose the fwd camera, in other words, too fast to really be messing about with screen controls. Harumph.
I would bet full voice command is coming soon. You just say "Car! Seat heater on 2!" and keep your hands on the wheel...
