Municipalities don't have airspace regulations. That's all managed federally. Also the Alpha Electro is already legal to test. It's apparently registered as an Experimental aircraft in the US currently, which means it can be used by owners but not commercially (e.g. for flight training). The market Pipistrel's aiming for is the Light Sport Aircraft category, but electric planes can't be registered as LSA in the US so Pipistrel would have to go through the standard airworthiness certification process. Which is long and expensive.
