That was exactly my point. Car CAN be fixed without the software.
It just takes more time (and knowledge).
If you are an owner of a repair shop then that is probably deal breaker. You can't hire actual engineers to fix cars, the cost would be prohibitive.
But nothing is stopping you to fix the car (except if manufacturer like John Deere makes it their mission to stop you from repairing it).
If electronics is broken your mission is to find the broken part and replace it, not reprogram it, which is basically the same as with mechanical faults.
