The fix doesn't help much for already affected systems, as they're even unable to boot. Only workaround is to manually delete the files in safe mode for every system one by one, which is even more difficult if it's bitlocker protected.
Absolutely crazy that they managed to screw up this bad.
Yes that's true. They still map out every intersection, sign, signals etc. Probably it's much safer for a L4 system to have HD maps when compared to a L2 driver-assist.
