This is absolutely unacceptable. I wish the relevant regulatory body would pull out the type approval for all Teslas until this update is rolled back, it's that bad.
If you own a Tesla, file an NHTSA complaint and say as much to them. They could well do so tomorrow if they can find sufficient rulings already on the books about this and enough legitimate owner complaints are filed.
(I don’t like my advice here, now that I’ve had something to. File a safety complaint, not a feature rollback request. They’re more likely to listen that way.)
The fact that Teslas have been permitted on US roads at all since Autopilot rolled out is clear proof the regulatory body isn't functioning as it should.
Teslas should be illegal on US roads until Autopilot is removed, renamed, and retooled, and significant oversight is put into place in Tesla's production and software release processes.
Ten years after I bought it Toyota warned me about the possibility some third party service people might've installed an improper part which could cause a problem. Tesla sometimes ships their cars from the factory with pieces of wood in them they got at Home Depot.
"Move fast and break things" is an absolutely intolerable attitude for a car manufacturer.
