It looks like it's a capacitance sensor, like modern touch screens, so unless that shrub has some weird electrical characteristics it shouldn't open the door.So the first shrub that brushes against the driver's front fender while off-roading may pop open the charge port door? I'd be much happier with a modest "soft-touch" mechanism that pops it open enough to grab. Basically like decent gas covers.
I agree though that I'd prefer a simpler mechanism. The sliding looks cool, but I imagine it'd get old 5 years in when I just want it to open and it won't.
