You know it seems to me that someone broke through Microsofts Firewall a number of years ago and saposedly that was impossible. The Titanic wasn't sapose to sink either..... EFI Live wasn't going to support LBZs etc etc. Things change. In a world of performance enthusiasts, I doubt these trucks will ever be unhackable. If it does get to that point there will be a growing number of companies with Edge style boxes or Zeus style ecm's.
Our government is full of a bunch of ignorant politicans looking for a way to line their pockets with money. In the mean time they just keep kicking the can.
