Doesn't matter if it was or wasn't, it was a failure that GM never followed up with. Why it was a failure is also irrelevant, because whether you feel it was a technical failure or killed by GM, GM never did anything with the project or knowledge. Effectively it was a curiosity.
>If GM killed it to keep it from succeeding
They didn't, and this is just absurd.
Not only were electric cars available since the very beginning of cars, but they've always been available as niche options. There are tens of electric cars that postdate the EV1 and predate the Tesla. Do you even know their names?
We have stupidly cheap gas. An electric car has only ever been a curiosity for America. Even now, the primary driver of people buying electric cars is ideological, and a mild convenience of never having to go to a gas station.
Pre-lithium battery electric cars are a huge hassle, for very little gain, even outside the US. The history of cars is a global one, and no amount of conspiracy theory about GM can counter the fact that nobody else made electric cars either, even in places with drastically more expensive and unreliable gasoline.
They have always been a novelty, like hydrogen and LPG and compressed gas engines.
Hybrids were the closest anyone got to making older battery chemistries meaningful for car-style transportation, and even that was extremely limited.
About compressed gas, they have so much cheaper fuel that they are the norm here in Brazil for Uber drivers. So, not a novelty
Brazil also pioneered flex engines that work with either alcohol and gasoline, and gasoline in Brazil is sold with high alcohol content
I agree with this.
Cheap gas, car culture and the incredibly long distances makes America a very different place from the urban centres of the Netherlands, China and Korea.
If GM killed it to keep it from succeeding, then there is massive precedent to never reuse the tech. In fact, their NiMH battery patents were sold to Texaco/Chevron who held them close and never let anyone use them. From that point, they couldn't follow-up without dumping even more cash into it, effectively burying it. Until new lithium battery tech matured, there was no way to do it again.
