> Car companies make their money from selling new cars, not keeping old ones on the road. I'm interested in how this could be realistically changed. I'm convinced most of the environmental and societal problems caused by economic activity is inevitable at scale, where an organisation's behaviour becomes dominated more by underlying economic rules than any principles it's originators may have had at a younger age or smaller scale. It also shouldn't necessarily be so specific as "must maximise vehicle life", it really depends, because it's not impossible that with the right manufacturing and recycling techniques shorter vehicle life could bring down the total environmental and societal cost. The question is how to make that economically interesting to the manufacturers, e.g what if each manufacturer was responsible, end-to-end, for the recycling of it's own vehicles... shorter vehicle life could mean more sales, but could also mean more recycling. If the process is optimised for that then it could be profitable and cheap for the consumer and good for the environment, but if not it will hurt their bottom line.
