GM knew that it wasn't worth pursuing cars with less than 200 miles of range and the market wasn't actually ready for an EV anyways. I doubt many people would be willing to buy a 150 mile range coupe besides the tiny number of enthusiasts.
What kind of crap point is this? Being the first to produce a new technology or product doesn't guarantee that you will be the market leader indefinitely. You do realize that Apple wasn't the first to make smart phones right? Sometimes it's better to sit back and watch how someone else does something first so you know how to improve it and it's easier to improve the design when you didn't come up with the original - the sunk cost fallacy is a thing.
The EV1 was a great commuter car (did I mention I had one for 3 years?) with a great trunk for running errands but it could not be one's only car as a Tesla (and maybe MachE) can today. I know plenty of people with compliance EVs today that have much less range than the EV1. I, myself, even managed to put over 100K miles on a 1st gen Leaf as my commuter car, reducing the wear on my other cars and easily paying for itself. The problem was that GM, as a whole, didn't want to make EVs. They were too deeply invested in ICE technology and its associated business strategies. Clearly, you didn't read the Schnayerson book I referenced. The EV1 and its successors could have gone 200 miles, even with NiMH batteries and some good design. GM knew it but chose to hit the brakes, not the gas.
You also are apparently not a technology developer.
I hope you do drive an EV at least, even if you don't really understand how it got to you.
For work, I had a Handspring Visor; after that, a Nokia Symbian smartphone; and later, a Handspring Treo. These were all prior to the first iPhone. Personally, I prefer an old fashioned flip phone with good audio quality for the most part, however.
There are 2 tech business strategies, each of which sometimes work if one executes well:
1) Early bird gets the worm (if you are smart enough)
2) 2nd mouse gets the cheese (if you are tenacious or rich enough)
Over the past 30 years, GM has repeatedly blown it on both strategies with EVs.
1) They were the early birds but let the worm go. They skimped on the NiMH batteries and, later, stifled fast charging technology
2a) They followed the Tesla Roadster with the Volt and blew it. They made the drivetrain to complex and expensive to put in along with expensive batteries and lost money on every car so badly that economies of scale (which the blocked) couldn't solve.
2b) They followed the Model S and beat the Model 3 to market with the Bolt, then (so far) have stifled its rollout so that economies of scale haven't made it a money maker either.
2c) It should be interesting to see if they can actually release the HummerEV before Tesla's CyberTruck AND make a business of it. To make a business, they'll need to quickly milk the high-end truck business with the HummerEV but follow up quickly with something more mass market like a Silverado, Yukon, Colorado, and/or S-10. Otherwise, sadly, I suspect it's their 3rd strike and they'll go the way of Packard, Edsel, and AMC (or similarly, the way of Kodak, Conestoga, or Smith Corona).
