I've got to say I've done a few long (>1000 mile) road trips in my Tesla and I've never once had to wait for a spot to plug in. There's also usually at least one other Tesla charging at the station. Which means they're successfully walking the line between underbuilt and overbuilt, capital efficient while also satisfying their customers. Most non-Tesla charging stations I've seen are under-utilized and often broken. I think Tesla could build Superchargers faster if they wanted to. If you overbuild, the chargers will rot (the plugs can need maintenance and replacement from weather exposure after 5-10 years if for no other reason) and you're paying expensive utility connection fees.
