Sam is back to talk about hands-free driving technology and the regulations that may be in the way of its development. The process of creating an autopilot has been an evolution as car manufacturers and government regulators seek to figure out the safest way to do it. Elon Musk complains that regulations are in the way, but they are there for safety purposes. But now Europe has put forth regulations for level 3 systems designed to make the development of hands-free steering more harmonious. The regulations require the driver to be supervising 100% of the time when engaging the hands-free system and must be ready to take over at a moment's notice (no getting in the back seat).
Level 4 would be total automation, where human intervention or supervision will not be required.
