1. Mike's explanation is totally off the mark. Tesla's systems are simple helpers that work in specific circumstances only, and still require the driver to be responsible/react. The technology has been around for quite some time now. Google is building a complete self-driving car that basically replaces the driver altogether. This is much harder and you need to get it 100% right before shipping it, as your system will (most likely) be responsible for any accidents it causes. The "expert" seems to confuse robotic wayfinding with the challenges that exist for self-driving cars. There is a (very small) overlap, but the hard problems are not in this overlap.
