It's time for another ... Tech Intervention. 

Nissan this week unveiled some new self-driving tech that, we believe, does not need to exist.  It's a fleet of self-driving chairs.  The chairs are meant to move people along in a line. Each one senses the chair in front of it, and then scoots you along so you don't have to stand while you're queued up for your cronut.  

The chairs are only going to be released in certain restaurants in Japan in December of this year. But I think we can all agree that this is a microchip too far.
