Funny you mention that. In this video it said that back in the day of "horseless carriages" there were actually more electric cars than gas powered. But they were push out by to oil companies.
And they were able to be pushed out because oil driven technology was better. Turn of the century electronics was rudimentary, batteries were nothing like we have today, and there was no way for them to compete with the gasoline cars.
Battery technology would not have evolved fast enough even if the electric car had gained dominance. This is a time when the transistor wasn't even invented yet, and the vacuum tube was just beginning to be a reality. Radio was barely accepted as a technology, Tesla had just recently invented it.
Around 1900 when Tesla invented his remote-controlled boat, it destroyed the notions of electronics at that time--it was beyond state-of-the art. One can view the patent for it online. Look at that obfuscated mess that took a genius to construct and then reconsider the plausibility of any electric car in that time period.
Look at the inefficiency and huge size and extreme danger of batteries in German WW1 and WW2 submarines--they pushed the battery technology forward, and they were still inefficient, and this was 40 years after the dawn of the car.
Would you drive a car which would be mostly battery, contain deadly acid, and put off deadly chlorine vapors? I wouldn't.
Today, over 100 years after the dawn of the car, we aren't much better off on the battery front.
The gas station "quick refuel" argument is probably the best answer to why the electric car is still a distant reality.
Maybe if the electric car didn't have to carry its own power source on board, but that is just a Tesla pipe dream. (Socialism fails)
There's no conspiracy, just fact.
