Okay, so for the moment leave aside the safety critical bits (only for a moment) - what's the excuse for not opening up the center console? That generally is already segregated and only handles non critical functions.
Center consoles have been used quite successfully as beachheads by hackers to be able to get into more important systems because car manufacturers are typically utterly clueless when it comes to security. So obscurity is a very large part of their security. Of course that doesn't really work with the most motivated parties (car thieves and their captive techies) having a field day with this.
Hyundai and Kia are reportedly so bad that they ended up paying out a large amount of money to compensate owners.
