I have a riddle, and I can't figure the answer out.?

On a dark and rainy night a hitchhiker was having no luck finding a ride. Finally a car stopped and he got in. But something was very odd - there was no driver! Suddenly the car started moving. The hitchhiker saw a curve coming up and reached for the steering wheel but a hand came through the window and turned the car. the ride continued, and each time a curve came, the hand reached in and turned the car just in time. Finally the car stopped and the hitchhiker ran into a bar, ordered a large Scotch, and told everyone what had just happened. Then two men came up to him. What did they say?
