Because they're incredibly slow and you'd need a giant facility to accommodate what even a tiny 4 pump gas station currently does? I live in Seattle and there are tons of Teslas, but the nearest Supercharger is way out in the suburbs at a mall so you can do something with all your waiting time.

I think the number of spots you need is actually similar. A car will occupy a spot for much more time, but it will need it much less frequently since it’s only necessary for long trips.

That’s why your nearest supercharger is out in the suburbs: it’s for travelers, not locals.

We're going to need a ton more spots, it only works now because almost no one has an EV and those that do are self selected to people who can charge at home. Somewhat ironically, EVs currently work best when you live in the suburbs and commute into the city. If you live in the city you likely won't have a garage where you can charge. Even if you drive to work and your work has parking and your work parking has EV spots at best there will only be a handful.

For sure we’ll need a ton more spots, but the total will be similar to the number of gas station spots.

For city dwellers, we really need on-street charging. That’s totally feasible, but there’s a huge chicken-and-egg problem to overcome.

Because charging points don't have the same environmental concerns as gas station fuel dispensers and storage meaning they can be anywhere. So why would you want to single purpose the land as most gas stations are. The convenience stores attached to most are designed to serve people in the time it takes to fuel a petrol vehicle which is five to six minutes max.

So chargers can be at places that encourage longer stops and since there is no real environmental impact that means they can be placed about anywhere a parking space already is.

Because if you are driving a PHV all-electric, you are probably charging at home, gas is a long-term range extender. Sure, as all-electric displace PHVs, that rane extender role shifts to charging points, but the big drop in demand for out-of-network fueling/charging comes from basic commuting being met by in-home charging.

Most people are going to charge at home (garage, parking lot, street charging point) or at work (garage, parking lot, street charging point.) That's not where gas stations are.

Because people will charge at their destinations or at home.

Think of it this way: You go on a long trip and need to stop for gas somewhere along the trip. Instead, you just plug in at your destination. That saves you a stop.

If you were going on a trip long enough that it requires a stop in an ICE vehicle you're going to have to stop in your electric vehicle. Maybe even stop twice.

Depending on how full your gas tank is, a trip of 10 miles could need a stop.
