Was done by Google Lexus RX450h self-driving cars a few days ago. They are currently in Austin, where Google, I mean Alphabet, is testing them to learn how to handle themselves on 'all manner' of roads there , how humans interact with them, gather data on driving conditions etc. So, when next you see them in your neighborhood, say Hello!OR hold up a sign..."hurry up! im tired of driving myself!"
when you meet in traffic.More photos below.
