That's 3 hours of downtime with my ICE, 0 minutes of downtime with my EV. Which one resulted in more downtime again?
In most cases having a battery will get you from A to B without issue - same on a tank of gas. When it won't, you will spend more time waiting on the battery to charge, which is a tradeoff that is probably still worthwhile for the vast majority of people.
> Similarly, for the sake of argument, I could keep a gas pump in my garage to fill up at night, which would mean I had "0 minutes of downtime" as well.
You literally couldn't unless you were massively wealthy or lived on a farm or something along those lines. You probably wouldn't be able to secure the permitting to have that much gas on site at small residential lot. It would also be a pretty big headache managing the gas delivery contracts for such a small amount. It would be a huge hassle getting it delivered to your home. Realistically, you couldn't get as much convenience at your home assuming you lived in a statistically average suburban/urban single family home.
Meanwhile all it took for my EV was to install an outlet, <$200. No crazy permitting, no massive storage tanks storing hazardous liquids, no managing additional delivery contracts needing to get big fuel trucks to pull up near the house to deliver gas, no EPA inspections for that storage tank, etc.
