Start by using singular feature roll out. We've seen lots of these little systems being introduced: sensors for blind spots, auto-braking, adaptive cruise-control, lane-assist, alerts for drifting out of lane, etc. Now they're telling consumers that driving is becoming automated while auto manufacturers have been slowly automating the driving process feature-by-feature for years. They're up front that it isn't unrestricted autonomy. That is, "Hey, this will keep you safe, but just in case, keep your eyes on the road. Don't worry though; these are the same features you've been using for years. "
This isn't a dumb entertainment system for showing off to your friends. It's field testing for future iterations when it is 100% automated. It's genius.
And it's been introduced in auto-braking, lane keeping, and other tech. slowly. It's all part of a road map toward fully autonomous.
The driver "keeping their eye on the road at all times" is just a legal requirement, since the laws are a big grey area for manufacturers, at the moment.
I'm not sure they're really all that grey. They're assistive driving systems and it's the responsibility of the driver to be in full control at all times. Now, as these systems get better and more comprehensive, it's reasonable to ask whether that's a realistic expectation. But it is the law.
Use the technology where it can actually save lives, like in auto-braking systems in case of accidents, and so on -- not in "autopilot" entertainment/showing-off systems where the driver is supposed to keep an eye on the road at all times anyway.
