It seems a fairly reasonable set of levels. For example, L4 seems like something that may be achievable in the foreseeable future if it means something like full autonomy on designated interstates in some weather conditions. That actually sounds like something that would be very useful for a lot of people (and probably a big safety benefit). It just doesn't do anything about eliminating private car ownership or the need to be able to drive at all. But, personally, those are of less interest to me anyway.
