First off, I'm so loving all the great features that are built into my CX-5.
a-For the keyless system, a design that one can know what's what by feel only, i.e. the 'lock' and 'unlock' buttons are different (see pict above, and it works!). What a convenience this would be.
b-A dashboard top that is matte black to lessen light reflection in the windshield for excellent, not just great, visibility (especially useful for those w/ a dash cam). Right now the speaker reflection is quite visible.
c-Moonroof and other windows that close after the vehicle is turned off, by use of their controls (don't know how many times I've had to restart the vehicle just to close the moonroof.
d-less blind spot percentages (can't the ends of a mirrors be slightly curved more to allow it to reflect a wider angle, especially to cover blind areas?).
Speaking of dash cams as mentioned in 'b', maybe mazda should have them as an option in future models. It's great to prove who's at fault in an accident, to capture perhaps even other accidents, to prevent insurance fraud, and to identify someone who might cause property damage to your vehicle. I'm sure it might help with insurance rates as well, so could pay for itself.
edit: e- FYI, I noticed with the first CX-5 I looked at, at the dealership, that the magazine pocket was torn. But later in our new CX-5 (not the one that had the torn mag pocket) when folding down the rear seats I noticed the rear seat head support was actually grabbing it and thus not allowing the seats to lay flat, and if you're not aware of why the seat wasn't folding down all the way you might just apply enough force to rip the magazine pocket.
