Actually, this makes the feature less useful to me. Let me explain.
If you've ever gone to a star party, where amateur astronomers set up telescopes to let people look at the beautiful night sky, you know that headlights are one of the biggest distractions and detractors from the fun. Every time someone gets into their car to drive away, the super bright headlights shine directly at viewers, who get a painful flash before their face now need to wait a minute or two to have their night vision adjust again. It's super annoying.
Because Air immediately pops the lights right back on as soon as you put it into drive, this makes the Air a terrible star party vehicle. It would be much better if I could drive down the road just a few feet to get out of the way of the telescopes and viewers, THEN pop them on.
Chances I'm going to not notice my lights aren't on in the pitch black of a dark sky area: 0%.
Chances of getting yelled at as I'm leaving the parking lot of any star party: 100%.
