I'd like to make sure there is professionalism and safety is a priority in BOTH places. Code review is just one aspect.
Industry is probably further ahead than you imagine, look up SIL.
Open-source just isn't going to happen in auto or industry. The only people who will spend time looking at it will be the competition (who would love to see your product fail), or students who have spare time but no frame of reference. Neither is a comprehensive means of reviewing code in the proper context.
An independent (and closed-source) code review should be a part of some industries. But it has to be conducted according to those specific industry norms and testing specifications. That takes years of experience and typically a committee of professionals from that industry to define.
