Well, my point is that Tesla's implementation of level 2 is a "hands off" design while other brands are much more comfortable to drive hands on because of the symbiosis between driver and car.’L2’ is a very broad category stretching from adaptive cruise on one end to Autopilot and FSDb on the other. The blended system you describe is somewhere in the middle. The key issue is one of driver expectations. in L2 the driver is responsible for the car, even if the car’s currently doing everything. As such the driver is expected to pay constant attention and take over at any time if necessary.
Poor design from Tesla that induces complacency.
But, they designed it back in 2014/5 and implemented it without nags - a different time.
