I've used that feature on my BMW for 8 years. I think it's great. I have yet to experience it happening "accidentally" when I'm wearing my "skinny jeans" There are some pretty vocal people in the BMW forums , but BMW never disabled that feature. AFAIK that feature is still available in current BMW models.
I do think that it is funny when people complain about it. After all the times I've used that feature on the BMW, I've never had the need to roll all the windows back up before I actually got into the car and got ready to drive away. That few seconds of venting all the windows, and even the sunroof, before you get to the car on a hot summer day in Texas really makes a difference. I wish that feature was available in the tesla. If it was available, I would definitely use it during the summer. Venting the pano roof just doesn't seem to have the same cooling effect as rolling down all the windows as you walk up to the car.
