Alternatively, they could also share their data in an open way and some device in regular cars could pick it up and use it to assist regular drivers.<p>I think both scenarios are possible. That data is valuable so maybe Google doesn&#x27;t share it. Sharing it would create quite a bit of goodwill towards their cars so maybe they will. It&#x27;s an interesting strategic decision.
[not sure about data protection laws but maybe they can&#x27;t share it even between Google cars unless the owners opt in]
