I remember in the 80's coming back from a Van Halen concert, four of us in a 70's Buick Electra (Deuce and a Quarter) ... guy named Bob was driving, we were totally ripped. On the Interstate .... I'm in the back seat .... we pass our exit ... ok, ... we pass the next exit ... I reach up and tap Bob on the shoulder and .... he wakes up! He had been asleep for about five miles and that 225 drove itself just fine ... who needs a Tesla
