I'm not even sure it counts as level 3, it's more like a high-end Level 2 system. Level 3 requires the car to detect "all" conditions when something is going wrong, and provide the driver "sufficiently comfortable transition time". If there is any class of event (such as a 1m overhang) which the vehicle can't safely cope with (perhaps coming to a complete stop before requiring the driver to take over), then the driver really has to be paying attention all the time, making it a Level 2 system. And there is basically no way to deliver on that promise on today's highways without a suite of sensors and computers that are capable enough to do full Level 4.
