Locking the doors after you drive is simply a safety feature. I would never drive around with unlocked doors. That being said, it would be kind of annoying to have to push a button everytime you drive away.
Sure I could push the button every time but many (non-luxury) cars already have this feature--so how can you pretend to be a luxury vehicle without the luxury conveniences?
Auto-unlocking is a bit more controversial, but it's one of the features I like about my car now (doors unlock when key is removed from ignition). It's really nice not having to push another button just before I get out and it helps with getting the kids in the back.
Of course, these features should be user programable. These are minor things, yes, but the fact that they have been left out just shows the cheapness of Acura--just like the fake wood and the non-leather 3rd row--hardly befitting of a "luxury" vehicle
As for the dusk/dawn headlights, maybe that's not such a bad thing judging by the number of people I see who drive in the evening without
their headlights on :sheesh:! It must be because most people on the road are not true "drivers"--they're simply "commuters" more concerned with what's on TV that night or what they're going to have for dinner when they get home rather than paying attention the road and road conditions around them. It's unfortunate but it's sometime safer to build to the lowest common denomenator.
And an always "on" plug? My car is like that now and I'm too paranoid to use it--I always unplug my accessories when I leave the vehicle.
