electric cars arent really useful anywhere.

Most are intended to be used as commuter cars, which makes perfect sense with an EV. A drive to work and back is unlikely to drain a newer EV battery completely, especially if there's a plug available at work, and commuting represents most mileage put on cars. As battery tech improves, the market for EVs is going to expand beyond commuting, because they provide significant benefits in terms of maintenance and efficiency.

Should also mention that reduced mechanical complexity means that maintenance costs on EVs are likely to be very low.

Also, gas stations are literally everywhere (in the us)

Electrical infrastructure is more widespread than gasoline networks. The current limiting factor is not availability as much as it is charging tech, especially for quick charging. EVs just don't make sense if you're travelling beyond the range of the vehicle on a regular basis, and that'll be true until charge times improve.

The electricity that they get charged with produces emissions

Electric motors are inherently much more efficient than ICEs, because they don't bleed off as much energy as heat or sound. As well, the idea that the power grid produces equivalent pollution as an ICE would is only true where power is generated by conventional coal. Most regions in the Western world have at lease instituted regulations around carbon scrubbers for coal plants, which reduces emissions. It's much simpler to deal with emissions from point sources like power plants at any rate, so this is not a fair characterization of EV pollution.

From an operational point of view, EVs are unlikely to generate anywhere near the amount of pollution per mile as an ICE powered car, and are also cheaper to run. Where the real question of environmental toll comes in is with the batteries. The manufacture of the batteries requires fairly energy-intensive processes, and because they have a limited life, and replacement is rarely the economic decision once they expire. This means that after 10 or so years, both the car and the battery are likely to be disposed of, and without adequate recycling there will be a huge issue.
