Popular hacker warkit Metasploit now hacks hardware and cars

IoC

Internet of Cars. Bad enough to have crap security which requires physical access to a data port but to have it hooked up to the cell phone network is a travesty now that exploit kit has become easy. How long till hacked cars hack cars and spread mischief like a worm.

Have governments already weaponized exploit code to cripple vehicles? Wouldn't want robust security and isolation from other networks. That would cost a few more (choose your currency)s.
