The funniest joke

In the opaque fog, cars are driving one after another. Suddenly, one of the brakes in front stopped and the car behind hit the rear of the car in front. The driver of the car behind jumped out of the car and shouted, "Do you want to die? How can you suddenly brake here in such a heavy fog? " The driver of the previous car replied, "Let me ask you first, what is your car doing in my garage?"
