Re: Smart Summon used "more than one million times"
You can turn off telemetry on Teslas (two options). However people who buy Tesla cars actually trust Tesla more than they trust Microsoft.
Sending data back to Tesla means that everyones vehicles have a chance to get better over time, new features can be rolled out quicker and it is one of the only cars which gives regular OTA updates some of which is based on this feedback.
They don't sell you advertising, they don't try to upsell products based upon your data, they don't appear to be part of a government conspiracy so I guess owners take the risk that the data will be used for what it was intended for. It's also anonymised.
If they screw around with it, many will turn data collection off.
