"some are not: re: cars that drive themselves."

amazing...

Though I note it will not happen in our time frame as an un-tethered issue, it is on topic for those that wish to have a dialog beyond that consideration that may allow it to happen in our time frame..

What if in the near future you read Google proposing to populate a road way, or a municipality with sensor infrastructure, and smart roads become part of the news? They've done it with WIFI and other issues.

It's on topic and may, or may not come up again.
