Superchargers are rarer than gas stations but plentiful enough (in the US) for long trips if you mostly stick to interstates. Non-Tesla networks are also rapidly increasing in number.
Also you cannot refuel your ICE car at home or at your hotel while you sleep. This is a huge benefit to EVs that makes ICE range comparisons hard to quantify in simplistic terms.
The problem is I don't always stick to interstates. Even when I am on an interstate, there is a big difference between being able to stop every 20 miles and every 200 miles. The first means I sometimes refuel because we are at half a tank and someone needs a bathroom, while the later forces me to stop like it or not when I get to a charger.
Refueling at home is nice for when I'm home - 95% of the time. That last 5% is the topic here. Most hotels don't have a charger, and even those that do you can't be sure you can park in that spot.
presumably as more people buy electric cars (teslas), they will have to add more chargers to their network. I just drove from 5K miles down the east coast and back through middle of america in a M3 and i can attest it is very easy to filter out hotels that have chargers, and a lot more hotels have tesla chargers than I thought. I only paid $37 from NYC -> Jacksonville (via PA) because of hotel chargers.
