It seems to me that it must be, since we're going to have self driving cars depending on all the components in the car working within a tight specification. How can manufacturers assure that the customer's car is still safe and won't randomly kill people or become weaponized? This is presumably a liability issue, and obviously a marketing issue as well. (And instead of "encrypted" I read "authenticated".) Does right to repair also come with feature reduction? By this I mean... go ahead and fix your car and put in whatever components you want, but know that as soon as you put in non-official parts, the car won't drive itself any more.
