When the boomers are gone what will the appetite for cars look like?

 The 'appetite' for cars is going to decline. The boomers love affair with cars is based on a golden age when cars were cheap, gas was cheap, and roads were uncongested. The experience has been worse for each subsequent generation, such that Gen Z doesn't even like to drive and can't be bothered to get licenses. But we can't do away with cars -- dependence on them is baked into our built environment.
