I'm pretty sure there's still 5 years worth of exponential growth potential from people who do have garages or otherwise will have the ability to pay for getting a plug somehow, and from new construction that's already set up for charging plugs (I believe it's required in some places like California now?)
Then what will happen in the 5-10 year time frame is that EVs will be significantly cheaper than ICE vehicles (maybe not purchase price at first, but certainly TCO).
Is there electricity anywhere near where you park? Think about what it would cost to set up a plug. It might be quite a bit, but unless electricity is really far away, it's not a crazy amount either.
If buying an EV would save you a significant amount of money over a 10 year period, it's likely that you'd be willing to use some of that savings to pay to have a plug set up. Maybe you can't set up that plug yourself, but as long as you're willing to pay a bit extra over the cost of electricity, there's going to be companies willing to set up plugs along the street. Once investors see that the transition to EVs is guaranteed, I'm certain there will be a rush to put up chargers, since the company that gets a street is likely to keep a monopoly on that street for a long time.
The other way to get street side charging is simply to get governments to do it. That's what Oslo has done. They started out being free, but now there's a reasonable fee on them, and I think that's much more sustainable. With some luck in the elections I could see something like that happening in several areas of the US. It'll be much easier to sell this policy once EVs are a bit cheaper, so I think it's possible if democrats gain some control, especially if they gain some support for some kind of Green New Deal. It's a great investment to boost the economy long term. Generates lots of decent work in the short term, and massive benefits to the public in the long term since it'll guarantee them cheap charging, leading to big savings to operate their vehicles.
There's another way to think about it: setting up a plug for your car is a very tiny fraction of the work/infrastructure required for your apartment, which somehow you found the way to pay for (either directly, or through renting). This kind of work is relatively easy to finance if the demand is there, since it's an investment that's likely to last a very long time and generate a lot of value.
There's also the fast charging model, which can be OK if you have a car with a fairly large battery and don't drive too much. You might be able to get by with charging once a week, and you could probably do it at a location where you'd spend some time anyway, such as a supermarket, near a restaurant or exercise studio. It causes some extra wear on the battery, but not an unreasonable amount.
