I wouldn’t really call that a “complete crack” (although it IS cool). There’s an _awful_ lot more firmware in a car or tractor than the display unit, and arguably it’s one of the less important modules in most architectures. Cracked versions of Deere Service Advisor are much more meaningful to the kinds of repairs farmers perform than firmware exploits are.
