I don’t think they can upgrade to new cameras AND to HW4 for $1,000. Of course, why would Tesla upgrade everyone to HW4 if FSD might take HW5 or higher?If they are going to require HW4 to run FSD, they literally have 2 million cars they will need to upgrade.
That's $2B if it costs them $1K per car.
There is no way they will be acknowledging HW4 is required at the end of this month.
It will be interesting to see them walk that tightrope.
There are 2.3M total Teslas sold before 2022. Unlikely that Tesla upgrades cars without FSD purchases or subscriptions.
