The small car's engine roared as it trundled down the city street, cars passing to either side, most honking. There was the occasional middle finger thrown as well, as if for good measure. The noise coming from under the hood would have been fine, even welcomed, had this particular vehicle not been electric. It should have been whisper quiet, unlike the petroleum-fueled pollution machines that had preceded it. But the last gasoline car had been scrap for at least fifty years.
