EV has been tried with great success since the moment the electric motor was invented. Trams, metros, trolleybuses. The bottleneck for free range was always the battery - which was solved by the mobile phones. The electronics industry had the money to invest into batteries because of the premium that people were willing to pay for even minor battery improvements. And the economy of scale pushed it down to where a battery pack was costing less than the GDP of Australia and so viable in a car.

Hydrogen cars will become available only when hydrogen is used as a temporary storage for renewable energy. But probably even there converting it to electricity in industrial scale fuel cell will make more sense.

I wouldn't say solved here. Significantly improved into usability yes, but there are still big issues with batteries:

- their low energy density means it's essentially impossible to have a long range in a small car, every long range EV is necessarily quite large, yet still has a shorter range than a city car

- specific energy remains meh, contributing to weight inflation (though by no means the only factor here)

- low temperature performance remains dreary and something you have to manage (and possibly hack / work around e.g. if your car only does automatic battery conditioning)

- while I think fast charge times are a bit overblown as a single driver on long trips (because stretching / resting every 2-3 hours is a good idea anyway), if you have relief drivers and can relay they're a significant impediment

Not that I think hydrogen has any future mind. But EVs do have a lot of drawbacks. And the amount of power you need available to charge a bus fleet in reasonable time is significant if you do pure battery.
