Wondering...
Did it see the lights and think they were road-side markers, and it was heading off the road so tried to correct?
Does seem to be a bit of these things doing odd swerves.
There's a video on YT of some dolt driivng through parts of the UK with one in it's "autopilot" mode. Clearly not requiring the operator to have his hands on anything through most of this. Attempts at sudden lane changes, wrong lanes, all sorts of 'weird' and unpredictable that could be dangerous for other road users.
Do Tesla's come with the number of the suicide hotline stamped on them somewhere? Seems it should be a requirement.
Icon coz looks like a car and these things are (for now) rather evil.
