With just 72 hours of training data, this is an extremely impressive result, scientifically speaking. However, in terms of quality control/best practices in automotive, it's simply unacceptable to trust human lives with a monolithic black-box system. The reason to have modular building blocks in a production system is not necessarily better performance, but the must-have ability to test, troubleshoot, debug, fix and replace things by reducing the degrees of freedom - it's the ABC of engineering even in much less sensitive industries. So while N2N is going to be very useful for rapid prototyping, and perhaps setting the performance bar for other method, I doubt it will ever be used in production.
