Lots of other new cars have lane keeping assist and automatic braking, BLIS, adaptive cruise control etc, and so on with more capable sensors and can for the most part drive without input from the driver better than the Tesla
Self driving is a huge step on from these things though. Hyper cruise control is easy in comparison and that's what those features give.
Self driving means capable in all situations and all conditions. Not just highways.
...because if you stop listening to other opinions you end up in a divided society that has no way of healing.
