Today while walking after picking up lunch, I spotted a Tesla Model S in a parking lot. This is not an unusual sight in Mountain View. What did grab my attention, however, was I saw something, a yellow box if I remember correctly, sticking out of the dashboard as I walked by. Curious, I walked up to the driver’s side window and looked in. It was a big red industrial-looking button that’s universally recognized as “emergency stop.” It was labeled “DRIVE UNIT STOP.” I assume that what I saw was an Autopilot test car, as the button reminded me of what’s in Google’s self-driving cars. I was surprised that Google’s installation of the button had a more integrated aesthetic. 🙂 Other than the button, the rest of the car looked normal to me as I continued along my way. I get to see some pretty neat stuff in the Bay Area.
