Tesla has been taking the legal position in these lawsuits that Tesla vehicles are not intended to be operated without an attentive driver with their hands on the steering wheel at all times. I suspect it is technologically feasible to design a Tesla to detect: (i) someone is sitting in the driver's seat (seatbelt systems detect that for years); (ii) hands are on the steering wheel; (iii) the driver is attentive (not asleep and is actively monitoring the road). Are Tesla vehicles designed to blare a loud annoying sound for as long as the system fails to detect an attentive driver?
