The biggest 'vampire' drain on teslas is cabin overheat protection and sentry mode, but those can be turned off. And yes, tesla superchargers are almost everywhere and convenient but still 20-80% is only 60% of the charge of the battery. Imagine if a gas car took 20 minutes for every 7-8 gallons of fuel added how annoying that would be. 60% of the battery will get you maybe 160 miles of range. In America the average driver drives about 15,000 miles per year. At 160 miles added per 20-minute charge thats 1800 minutes or 30+ hours spent charging. That is only under ideal scenarios with only using fully functional 250kW v3 superchargers. I've very frequently found supercharger stations to provide much slower charging speeds caused by faults or other issues with electric demand. It can sometimes take 45 mins to up to 1 hour to get that level of charge each time.

It works out fantastic on roadtrips because it forces you to stop and take a break, stretch and maybe visit some local restaurant, store or roadside attraction that you wouldn't otherwise see. But, spending 30-40 hours per year at the same local neighborhood supercharger just sounds like no fun to me.
