Purchasing the car is an information intensive process, there are many opportunities to educate the consumer besides seeing a marketing video, for example: before checkout process, post-purchase communication, before you using the feature the tablet can have a mandatory information session, persistent reminders later during day-to-day use, etc, etc.

Negligence is already something the courts are well suited to handle. Tesla already has a big incentive to do this well. I don't think they are necessarily negligent here for having marketing material which doesn't 100% cover real world usage. If that was ALL the information customers received I would...but I highly doubt that's the case.

I also take issue with the autopilot name as well, but I do think it's something that can be effectively communicated elsewhere with a product like this - where it really isn't that big of a deal. It is not a large barrier to communicate the immature state of the software and the limited current use-cases to each buyer beforehand regardless of branding.
