Credibility is extremely low
right now, but at some point HW4
will be coming to the Model Y. If HW4 was truly
that important to a buyer, they shouldn't have ordered a vehicle when HW3 was still current. Automobiles, like nearly every other product, will continue to improve over time - you'll
always be waiting for the "latest and greatest" version. If you wait for HW4, then HW5 will come out in a few years making HW4 obsolete. Some people buy a new smartphone every year so they'll have the latest model. I don't understand people getting angry or disappointed if HW4 comes out right after they took delivery - it has to start somewhere. What do they expect Tesla to do?
