Today I had the unique opportunity to experience a fully autonomous – i.e. no actual driving required – vehicle, a prototype. From being a concept vehicle a few short years ago to now an automobile actually allowed on the road, Nissan’s EV-that-could has made incredible progress. I have included the video below, including a Q&A with one of Nissan’s engineers.

I like the blue and red lighting underneath the vehicle depending on the mode it is in. Blue = Autonomous, Red = Manual or waiting/evaluating? Aurir, was the red light indicating a Manual mode?
Red was illuminated when the vehicle encountered an obstacle requiring it to stop. Blue indicated everything appeared OK.
The entire time was autonomous.
