Got my Model 3 a few days ago and still learning it. I do have a newbie question - I drive in my garage; so when leaving and backing out, it seems the HomeLink button doesn't work. Tapping it, I don't see the 'transmit' signal. If I stop, and put it in park, then it will. Is this a bug or a feature? I want to be able to hit the button after I am out, but still backing out. We have a long driveway, and by the time I back out and turn, the garage door can close - rather than me waiting for it. Any ideas? Thanks.
