On a trip from Boston area to Vertmont yesterday in my S, a lost all sensors. No traffic, road lines, even the rain sensor. Re booted both computers, stopped briefly. No improvement. So, I had to drive manually towards Vt. Not even cruise control!! Stopped after a couple of hundred for electrons, coffee. When I came back everything was working!!! Nav on Autopilot all the way to my destination -- everything was great. So, some kind of software bug I'm guessing. At first I figured some chip had blown, but if fixed itself. Any else seen this??
