Not just in the US. The amount of chargers is growing by double digit percentages in many countries. Tesla's network is one of the larger and more mature/reliable ones but they are not the only ones by far and there are many billions being invested in this sector. Utilization of this infrastructure remains fairly low. Most of this is being done in anticipation of massive growth in demand in the next few years.
And while people obsess over fast chargers, the real deal is actually slower charging in parking lots, parking garages, shopping malls etc. Those are a lot cheaper and easier to install and they are similar in cost to what people would install at home. Basically, most of the charging happens at home or chargers like that while the driver is doing something else. A lot of venues try to draw in customers by providing them with charging opportunities and they are fairly cheap to install. There are already quite many of those. Hundreds of thousands of them. They're everywhere.
You use fast chargers at a premium when you have to on longer journeys. Plug it in for 20-30 minutes and continue driving for a few hours. Not that big of a deal.
But slower charging is better for your wallet and battery and if you are parking the car anyway, you might as well plug it in to gain a few extra kwh. It won't delay you or cost you much. For most typical EV drivers, that's all they need most of the time. The vast majority of charging is slow charging and it doesn't involve people waiting for that. On average people only drive maybe 10-20 miles on a typical day. That's only about 4-6kwh. You don't need a fast charger for that. Plug it in at home once every few days or at the mall while you are shopping, having some coffee, at work, etc. There are plenty of opportunities for charging even if you don't have a charger at home.
