Thank you for this article! I vaguely hear about self driving cars but have no idea what that means. The levels you explained helped a lot. Do you think that once we hit a level 5 we won't have a need for anyone to be in a car? Say if someone goes out for a night of drinking will they just be able to get in their car which they will not have to operate to get home? I also wonder about how this will impact the trucking industry if we wipe out that occupation. I can appreciate how safe roads will (presumably) be once we have this technology.
