- Speech recognition
- VMax un-limiting (M Driver's Package)
All of those are protected using cryptographic functions and are very hard to break (as far as I know, only the first two have been done as of now).
That is how BMW protects things they are interested in, because these features generate revenue - unlike if they protect you car from being stolen, where the opposite is true.
Honi soit qui mal y pense.

Oh please. You swear like this wasn't a highly sophisticated attack utilizing hacked key replacement equipment to begin with. Oh yes, this was a bunch of retarded 18 y/o gang bangers that just busted a window and took off in a car. No.
The car is plenty secure, and BMW has already offered a solution. Shit happens.
Furthermore, even HIGHLY cryptographically encoded data, like the HDMI key signing algorithm, are cracked just as well. I don't care what encryption you have, you won't be safe for too long.
