The Nissan Leaf already gets 100 miles on a charge. And the Tesla Model S gets 200 miles on a charge.
These are all based on daylight, 70 degree day, no ac and new battery. The electric car will always be a limited application vehicle..apply cold, heat and age and they are limited to short range operations.
Some of the golf cart users here in our neighborhood(not a gated community) have switched back to mini-cars and smart cars. Once they got hit with aging batteries and replacement costs..they aren’t that cheap anymore.
Tesla S range is 125 miles for the base model based on EPA testing, but yeah, we already have electric cars with such range.

Not for long, depends on a lot of factors and battery age. Lots of leaf folks are unhappy at how fast the batteries have lost their ability to hold a charge.
Until you can get a 300-400 mile range and a 5-10 minute recharge the purely electric vehicle is nothing but a commuter vehicle at best, its not a practical replacement for the internal combustion engine.
Someday we may get there, but aren’t there yet.
Frankly why don’t we just put this money into teleportation, then we can be done with cars in their entirety.
