Yes I am aware of that, however the current way that is being looked at addressing the problem is moving the cabling to further within the car, which is just pathetic, like thieves wont just adapt to that.
Encryption really isnt as big a performance impact if it is done correctly, sure it is not cost neutral but ask Range Rover how much reputational damage they had with their piss poor security. They are still having 1 in a 300 brand new defenders stolen after adding what is pretty a traditional immobiliser and tracker.
As an example: https://iopscience.iop.org/article/10.1088/1742-6596/2006/1/012071
"Done correctly" is the trick. This takes careful analysis and design. You don't just pour on encryption and hope everything will be fine.
