My last two vehicles came equipped with auto locking doors and auto lights on at dusk. My new Honda Odyssey does neither. We blissfully ride with doors unlocked as we seem never to remember to push the button.
Last night as I pulled away from my sister-in-laws, I mentioned that the dash was dark. My wife told me that the headlights were probably not on. Yep! Old habits are hard to break.
However, this car has a most aggravating chime every two minutes if the seat belt is not fastened forcing me to finally wear the damn thing. So I guess I'm safer as I head down the road in the dark with the doors unlocked.
