Sure, but you're missing the point. EVs have not come a long way over the past 100 years, because battery technology sucked, and still sucks. The key problem the entire time, has been batteries. And you can't claim "well if the automotive industry actually put money into R&D it would be better", because that's simply not true, as many other industries also rely on battery technology(everything from flashlights to forklifts, some of which are made by auto manufacturers) and the combined efforts of those industries exceed anything the auto industry would have been capable of on its own.I'm comparing how far ICE has came in the past 100 years (a long, long, long way) and saying, in 100 years from now, electric will probably come a long, long, long, way.
And you're right, it would make more sense to use a hybrid fleet of vehicles, as current battery technology can definitely supplement ICE. Hell, look at the diesel electric locomotives that the train industry uses. Run the ICE generators at their peak efficiency, then use batteries to store any excess while powering the train. The chevy volt actually did that, but that's out the window. The other key problem with a lot of these EVs and even some hybrids, is that they're also little econo-shitboxes. The BMW i3 is trash, the Volt was a cheap econobox, the Bolt is still a cheap econobox. There was a hybrid cadillac, but it was just a chevy volt with different body panels and an outrageous markup. Most people don't want to pay $30-$40k for the equivalent of a Nissan Versa for everything besides the drivetrain.
