> I was a kid during both oil shocks of the 1970s. That has absolutely nothing to do with my driving. What does, and not just for driving, is the family taught cultural value of 'don't be wasteful'.
For me the 1970s were drought and a lifelong awareness of water conservation. Edit to add: buckets to collect water from "warming up the shower" and using them to flush toilets must be one of my earliest complete memories of a complex process.
If anything, our family culture of thrift came from parents who were small children during WWII rationing and grandparents who were children in the Great Depression. I sometimes can even imagine there is an epigenetic factor here, leading to more obsessive (compulsive?) planning, optimizing, and risk management behaviors...
This is most likely caused by those oil shocks.
