true autopilot would be level 5. we're not there. that's jetson kind of stuff. but maybe it gets in the head of drivers in a way that makes them overly reliant on those -- those abilities that the car has, or doesn't have? >> yeah. i actually do think words matter. we should not be using words like autopilot and full self-driving is. because it does convey to the people that the car is more capable than it is. i can assure you right now there are a set of people on twitter angry we me for speaking out. i want to be clear, this isn't just a tesla problem. this is problem is going to be increasingly in our faces as we start to see more quote/unquote hands-free driving from other cars. yes, indeed, that phrase which is not a tesla phrase, it's for the rest of the automotive industry, i think we should get rid of the phrase "hands-free"
