My 2 cents:
I carefully played with the handles on #65 (so, not sure if they are representative of the final product), but they were definitely capacitive for extension and motion sensing/IR for open. Lightest touch would extend the handles, didn't have to touch anything (like playing Doctor!) to hear the latch go (but required a pull to really open the door).
For me, the timing like this (thus, without the electronics package) was just the slightest smidge slower than I would like - but really, not slower than the Roadsters tap-and-pause buttons.
With the electronics package, I would be so diggin' on them. I'm pretty convinced they'll be darned slick.
(Where's my AWD Model W with all this stuff?!?)
