Although Elon has said that HW1 AP features will continue to improve, I don't see any incentive for Tesla to continue improvement in HW1. The number of HW1 cars are now fixed, and will be dwindling over time as they are taken out of service (e.g. accidents, etc.). The number of HW2 cars are increasing by the day, and with Model 3 volumes, HW1 will be a tiny fraction of the overall Tesla fleet. I just don't see any rationale for additional HW1 improvements outside of standard fleet learning tweaks to current algorithms. Anyone agree / disagree?
