Agreed. Careful what you wish for. All those enthusiasts out their enjoying hacking their vehicles (in the traditional meaning of the term) would not like crypto and HSMs on that bus.

It's like in the old days when internet traffic was unencrypted and so was Wifi. You could have a lot of fun just watching what's happening in your home network, and perhaps your neighbors (so I heard..legal grey area). Today? Nope. Everything is locked down. Wireshark shows you only lots of SSL. And that's not even proprietary stuff as the car crypto will be. The bad guys will obtain the keys or workarounds somehow. The good guys will be locked out.
