> most people do not keep their gas cars filled to 100% in case they need to do that weekly emergency 300-mile drive that everyone seems to have The behaviour is caused by "ease of resolution". Low Petrol - 10 minutes to drive to the servo and fill up, almost guaranteed and no more worries. If a long drive, then maybe another stop. Low EV charge - where I live, maybe you can do a quick 10 minutes somewhere and get a long way and while you're travelling find another 10 minute stop etc. But people don't want to add extra "unknowns" - however small - in an emergency. People want certainty. People want "Problem fucking dealt with." Emergencies don't happen often, it really isn't optimal day-to-day behaviour. But sometimes emergencies matter; for themselves, their family, or their friends. So I don't think you'll stop this range anxiety until it is as easy - and well known to be easy - as dinojuice currently is.
