Driving along a lonely road, you come upon a stalled car and a motorist who appears to have run out of gas. You consider stopping to offer help, although this may cost you several minutes and some extra driving. Would your decision be different if the road were heavily travelled? If you were to run of gas, would you prefer that it be on a busy street or on a lonely road?
