Most inter-city roads at the time were dirt tracks, a situation that wouldn't improve too hugely until the New Deal in the 30s, giving a period of perhaps 20-25 years to build up a market, and it will take until the rise of the suburbs for electrics to seem like a really bad choice, by which time I'd expect quite some development in battery technology (not up to modern levels, but much better than what they were).
Last time I checked cars can drive on dirt roads, they do it all the time. Not the best for wear and tear but drivable. So you can go 30 or 40 miles on a charge, big whoop!
