1. Mike&#x27;s explanation is totally off the mark. Tesla&#x27;s systems are simple helpers that work in specific circumstances only, and still require the driver to be responsible&#x2F;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 &quot;expert&quot; 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.<p>2. The article linked is merely rephrasing the answer explained in a Forbes article instead of actually quoting the source. A simple link to the Quora answer would have sufficed.
