What is game 2 and how do I get to it?

"Try Game 2. Not only do you have to clutch and shift your racer quickly through four gears and give it the gas without blowing your engine, you also have to steer your Dragster between the grandstands and the center divider. You steer by moving your Joystick up and down. Any time under 6.20 seconds in Game 2 is sensational." - Dragster for Atari 2600 manual

In your emulator, press key bound to Select to play Game 2.

If you pressed it, number will change from 1 to 2. To change it back - press Select again.

Game 2 has exactly the same inputs for shifting too. Instead of trying to avoid the barriers, just do your game 1 inputs. Sometimes you get lucky and the dragster doesn't hit anything on its own.

Thanks!
