LANCASTER, Pa. (AP) — Pennsylvania utility regulators are making a big to-do over Timm Wenger's tuk-tuk. The 48-year-old entrepreneur wants to use his three-wheeled, open-sided electric shuttle to offer sightseeing tours of Lancaster, the urban core of a region best known for its undulating farms, horse-drawn buggies and large Amish population. Standing in his way, at least for now: the state Public Utility Commission, which licenses for-hire transportation services and turned down Wenger's application last month, citing safety concerns. "Instead of doing tours and growing the business, I've spent weeks dealing with the red tape," said Wenger, who has appealed the decision. Tuk-tuks were virtually unknown in the U.S.
