There is no viable alternative to ICE
NOW OTOH, in the not to distant past there was no viable alternative to animal power. (In my early teens I plowed the garden with a mule. I learned to love that John Deere A next day in the field) But then Hank put the T on the market.
Our society is totally dependent on ICEs for so much like airplanes, trucks, trains, etc for transportation of people and goods
The public health issue of the last few years has convinced many companies there is no longer a need to transport many workers to a office. Maybe our society can learn to produce more of what is needed near where it is needed? And go back to more rail, powered like subway, to move more goods and people?
Or will the average middle class joe have to go back to tent camping?
I see another, harder to fix problem for the "average middle class joe" with regards to camping. That is for a family to stay in middle class, afford to even tent camp, there often needs to be 2 or more full time jobs. And sometimes the only way to generate that income is several part-time jobs. Now how do you manage to get time off all the jobs at same time?
