No these are as important to the present world as air travel and sea travel. I'd argue that given the problems we must solve they are more important than both. Martin, your honesty is in question. You argue for Hydrogen (which is a petrol rescue operation) you're against real electric cars. And you're insisting on very questionable assertions regarding self driving. Sure bad unions don't want self driving nor does obsolete capital as it will drive guaranteed annual incomes and the elimination of phony wage slave jobs, with the bursting of the psychological bubble of denial. But more than any of these groups petrol doesn't want it because it drives electric vehicles and electrification into every area of life and therefore fuels true green energy like battery backed solar like nothing else. You seem to have some ulterior motive and my guess is it would be financial, either these changes run counter to your investments or your families investments or you're being paid to write these things.
