That's not Tesla's issue at all. The Model S is
not a fully autonomous vehicle. There are different levels of autonomous control, from 0 to 5. 0 being cars most of us drive, and Tesla's Autopilot is level 2. There are no publically available Level 3, 4 or 5 in the US...that's still technology under development (Audi has Level 3 capable cars, but not clear if they'll be offered here). Tesla's Autopilot is meant to be an aid and NOT something where the driver can start browsing their phone or working on their laptop. As I've said before, infrastructure technology is a huge reason why...Autopilot is easily confused by poor lane markings or objects it can't quickly identify. However, people leap to the conclusion that it can drive itself. It can't, it can only do limited things, with the driver ready to take over at a moments' notice. As a side note, Tesla is running on hype...don't be surprised if they crash and burn (figuratively) at some point. Their automotive business is far from profitable. They're pioneers for sure, and I love the Model S (hate the X...ugh) and the Roadster that came before it, but they're not on solid footing by any stretch.
Oh, and I don't drink alcohol, so I'll take a caffeine free diet Coke in 10 years. Thanks!!
