In 1975, I was flying from DC to Detroit for a meeting at the Tank-Automotive Command in Warren. Mt seatmate was from the Dept of Transportation and was going to Detroit for a meeting on something. We were both originally from Detroit and were discussing public transport in Detroit. he assured me that once gas got over a dollar a gallon that no one would choose to drive to work but would take public transport only. I said that people would never want to give up the freedom and independence of their cars.
