RALEIGH, N.C. (AP) — North Carolina has become an attractive market for smartphone-based car services such as Uber and Lyft, which are drawn to the state's mid-sized cities that have college students and young professionals but lack extensive mass transit. It's also one of many states where little regulation exists outside of traditional cab and limo services. Uber currently offers rides in 10 cities in North Carolina, ranging from Wilmington and Asheville to the larger Raleigh and Charlotte.
