Make hay while the sun shines. BYD will force self driving to table stakes in a few years.
Once they are established they will require a subscription, or they will stop support after a few years so you have to buy a new car or pay more to get extended support.
Whatever it takes to extract more money from you.
Not just BYD, huawei solution is almost at par with Tesla. German, Korean, Chinese all will be there in few years.
