To Summarize: The green car in the middle of the screen is Johnny's car. The yellow one is yours. Johnny's car is always maintained in the middle of the screen. If you look at the white fence posts screaming by above and below the road you can get an idea of how fast Johnny is moving. When a car drives off the front or back of the screen it will reappear at the opposite end, pretty much as if the two ends where joined to make a loop.

 There are a few things you can modify:

• # of Cars: There have to be at least two cars, there can be as many as you want.
• Following Distance: How much risk do you want the cars to take? The smaller the following distance the closer the cars will follow, and the riskier the driving will be. Luckily everyone is driving Nerf cars, so accidents don't cause an explosion or anything. They still slow traffic down though.
• # of Lanes: There will always be at least two lanes, you can add more to make up to nine.
• Ambulances/Pace Cars: Are you and Johnny driving ambulances or pace cars? The difference is in the allowable maximum speed. The pace cars will only go about as fast as the fastest of the other cars. The ambulances want to reach the speed of sound.
• Auto Drive/User Drive: You can have the computer drive your car. This is probably the most fair mode to use if wagering is involved. When you are driving your car there will be two extra buttons, "<-" and "->", used to change lanes. Even in user drive mode the speed of your car will be automatically controlled.
• Lap Count: This records the lap of your car compared to Johnny's car. You can make this lap count go up by becoming more skilled.

• Cars off the screen: The game will only let a car reenter the screen (after moving off of it at either end) when it is safe to do so (i.e. when it can enter the lane while maintaining the following distance with the car in front and behind it). Because of this, the number of cars on the screen may be less than the total number of cars desired. For the sake of "fairness" though, your car will never get jammed up in some long list of cars trying to get back in a lane. It is given the first opportunity.
• Light speed: When driving the ambulances the cars can get going so much faster than any of the blue cars that it would never be safe for the blue car to reenter that lane. At which point the game becomes boring, as the ambulance will just scream along at a thousand miles an hour for ever. When this happens just hit the "New Game" button and refund yourself your quarter.
• No radio buttons: I should have used radio buttons for choosing between UserDrive/AutoDrive and Ambulance/PaceCar, those things where there is a list and you can only select one item. But, I couldn't be bothered figuring out how to do that. This is my first Java program though, so maybe I will eventually.
