Comfort and Convenience
Power folding mirrors retract on command, but the glass angle itself is set separately: a driver aims each mirror first, and folding then returns it to that same aim without re-adjustment.
Safety and Driver Assistance
A driver's airbag only deploys once an impact has begun, so it changes the outcome of a collision rather than preventing one. Braking room ahead is still what avoids the contact entirely.
Multimedia and Connectivity
A Hi-Fi audio system describes how sound is amplified and reproduced in the cabin; it says nothing about which phones or file formats a source connection will accept.
