EV owner here. 50 miles is not practical, beacuse then I need another for the other 2% of trips that are longer than that. This also ignores detours or traffic jams, when google will try to reroute me over a longer, but faster route. Plus, the "50 miles" readout you get is always just an estimate and the real range depends on temperature, driving speed, start-stops and how much elevation you need to cover. Some 30km trips here cost me 50+ EV km because its all uphill in one direction. I usually add 30km to my trip as required charge, because when the battery reaches 25km the car starts to complain with a nervously blinking battery readout and a "Charge now!" message on the dashboard.

"But then you just charge during the trip!" - Well this only work if i go somewhere where i know where to find RELIABLE chargers. I am well aware that there are good apps that show me charging locations, but getting a charging spot I can actually use is a different story:

charging station can be used by someone else, or there is queue and each car will most likely charge for 30+ mins. Of course, sometimes some inconsiderate pricks will hog a spot untill their car is fully charged, even if it takes his frikkin tesla 2h
charging stations close for repairs, sometimes for weeks
some charging stations need an account or RFID-tag before you can use their (but not other) charging network
other charging stations require you to bring your own cable
some charging stations dont have the connector you need for your car
some stations on the map are bogus, for example that one at my local volvo dealership that only exists to charge the showroom and customer cars, but is not accessible to the public.

Not saying EVs are bad, but the charging infrastructure still needs some work to be reliable and accessible. Petrol stations always have some large, obnoxious signs on the side of the road that you cant miss; Charging stations are sometimes just a tiny grey box on a wall and a 5-space parking lot, or behind a building and you never notice it when driving by.

A lot of households, like my own, have multiple cars. We have a commuter (50 miles round trip) and a family car. We use the commuter for most trips around town (only commutes 2x/week), and the family car for longer road trips.

I don't need a car that can do both, I just need to replace the commuter since that's where the vast majority of our driving is.

Don't try to solve the hard problem of putting charging stations in the middle of nowhere, solve the easy problem of replacing that second car. For that, sodium-ion is more than sufficient. Focus infrastructure improvements on apartment complexes, workplaces, and shopping centers so people who don't have a garage can charge.

I wrote elsewhere about the infrastructure problem, but I'll sum up a couple things. There's around 200,000 gas stations in the United States. If there were an equivalent number of chargers around, having a small battery would be fine. Eventually this will be the case, but you highlight an important factor: closed ecosystems. All these chargers should work for any make of EV car.

As it stands with now, the need for a subscription or specific car or unique payment method is ludicrous. All these chargers should be required to have card readers the same way you can pay at the pump in a gas station. Beyond this, they'd all need to adopt the same charging method so people don't need a bunch of adapters in their trunk.

That said, there could be regulations established to require newly built housing, apartment buildings included, to have electric vehicle charging infrastructure - and more than just a few plugs. Grants could be made available for retrofitting existing buildings. If these things came to fruition, we wouldn't need two hundred thousand charging stations all over the place. It's not out of the question to install an overnight charging spot for every person that has an electric car - it just costs money.

Basically every argument I've seen against low range electric cars is founded in a charging infrastructure problem. Going to a bigger battery in a larger vehicle has significant and more costly ramifications on other infrastructure. It's better to aim for smaller, lighter vehicles with infrastructure in mind.
