But people are angry when manufacturers release EVs with a 250 miles range because it's not enough but more than that requires batteries so big it becomes ridiculous so the alternative is PHEVs but then you need to reduce the battery size to make space for the engine so the electric range isn't as good...

BMW had the right idea with the i3 though, 650cc gas generator with a 10L tank to just keep the battery charged for an extra 100 miles so your range is technically unlimited but you still have enough space to have a battery worth talking about.
