The start button (or app, or whatever) absolutely does something, and to say otherwise leads me to think you need to dive in deeper to how they work.
The button closes the contactors, activating the high voltage battery pack. To do otherwise is a massive safety risk. It also verifies the key (to prevent theft, and required by law) and on some models launches the parts of software needed for driving.
I'm not familiar with Tesla's design, but it should be easy enough to set the code to run this process whenever the door closes. Whether that's what people want is a different question entirely.
Yeah Chevy got rid of the start button on the 2027 and it turns on* when you close the door. Its one of the common complaints I read about on the subreddit. It would annoy me as sometimes I dont need the car on and automatic things annoy me
Technological devices making assumptions always seems to be grating, and can even be disastrous. I'm not against automation at all, but it is important automate things only when the automated tasks are certain to be appropriate, rather than guessing, as in this example of the car automatically starting when you get in, when sometimes you dont want that.
