Driving a vehicle is complicated at the best of times. It involves the basic tasks of using the accelerator and brakes, as well as the clutch in manual transmission vehicles, besides watching for traffic, pedestrians, other road users, and animals. Except on very familiar roads, it also involves finding the best route to a destination, whether that involves using a GPS computer or using old-fashioned maps and looking for street signs. With construction, red lights, hills, and valleys, drivers are constantly facing situations they might never have encountered before.
