This winter, Charlotte residents and visitors will be able to travel for free in between Center City; First, Second, Third, and Fourth Wards; and South End in electric GEST carts. GEST Carts – which stands for Green Easy Safe Transportation, is debuting its Charlotte service starting Friday, December 17th. GEST Carts operate similar to car transportation services like Uber or Lyft. Charlotte riders can “call” a cart through the mobile app.
