I've always considered it a huge mistake how little funding and focus has gone into synthetic carbon neutral fuels ... it makes no environmental sense to trash the entire current transport infrastructure and replace it .... the environmental and carbon cost of that alone is monumental ... the ideal situation would be to continue to benefit from the environmental costs we've already paid of all our current hardware as long as possible, replacing as needed .... I suspect those who look at policy in the meta sense see this churn of ICE replacement as a driver for yet more expansionist economic growth (get rid of your perfectly good stuff and replace it with my nice new 'green' stuff ... which will cost you more but the Planet's worth it!!)... if it can be spun as saving the planet then so much the better, even if a proper holistic environnental audit would see it as nett negative in its impact.
