I usually carry my phone in my back pocket. It took me a few days to realize that I needed to twist my hip for the car to pick up the phone’s low-range signal. It didn’t happen to me, but a phone that runs out of juice could require pulling a near field communication (NFD) card from my wallet to open the door like a hotel room. I can see why some folks want buttons but, for me, the Tesla system of egress and ingress is progress.
