My quick take on the group components:
Blind Spot & Cross Path Detection - I hate the ugly sensors on the rear bumper. Don't want it, don't need it
ParkSense Rear Park Assist System - people, it's not that hard to back into a parking spot without computer assistance. Just look and listen. Don't want it, don't need it
Power Multi-Function Foldaway Mirrors - the once or twice a uear i want to fold my mirrors I can use my hands. Don't want it, don't need it
Universal Garage Door Opener - handy, but I can keep a remote in my console. Nice to have at best
High Intensity Discharge Headlamps - absolute must have. There is no going back to halogens once you've had HIDs
So out of the whole package the HIDs are the only piece I want and the garage door opener is take it or leave it. I can suck it up and live with overpaying for a bunch of idiot-proofing gadgets to get the lights, but I really hate those butt ugly sensors. They look only slightly better than the plastic push pins that hold plastic panels in place.
Why can't we have HIDs as an ala carte item?
Because profit margins. Always. I agree with you whole-heartedly regarding the importance of HIDs. Certainly more important for safety than the federally-mandated backup camera. Only a moron knows not what is aft of his car, but having the absolute highest quality and luminosity fore of a moving vehicle in the dark seems like common sense.
I'm wondering if the mirror upgrade is one that folds automatically when the car is locked, as with my wife's Q5. That would be ideal, and it really is functional for anybody who parks their car anywhere outside of their own garage.
Universal opener is nice, solely because I like everything that can be integrated to be integrated. That creates a classier, more expensive feel when I'm in the car.
Blind spot detection and park assist aids are for people who shouldn't be driving to begin with. Rear cross-traffic could be useful in certain scenarios, but not for all.
Question: Have you any photos of a '15 Challenger with the rear bumper sensors? I just ran through my folder of collected images and could not find one.
