If 7.1's Summon is a baby step, then I'm interested in what comes after the baby step. The 7.1 Summon? Not so much.
Elon clearly believes what comes after the baby step is autonomous, unmanned driving: your car is "summoned" from one place to another, perhaps down the road, or across the country.
Okay, but here's my thing: if EVER there were compelling reason to add more cameras and full-time video recording to the car, it'd be between now and the more compelling, ambitious version of Summon that is to come. The car desperately needs a black box, with fulltime 4-sided HD video running, not only for security when the car's unattended, but especially while it's driving.
We've seen countless topics in this forum about accidents and security incidents where cameras came in handy. Tesla should be building this into the car as a standard feature: cameras built seamlessly into the surface of the left and right sides of the car (we can debate ideal placement). They've already got cameras in facing front and back. So add a terabyte or three of storage somewhere deep in the car, and a password-protected way over wifi to pull down or interactively access the video as needed (including from the Tesla smartphone app).
If and when Tesla comes out with such a feature will be the time I just might have to turn in my ancient, clunker 2013 Model S for a new version.
