Use you back to keep him there(He's usually all the way over on the left side) Then he'll go slowly and then catch up with you again withing 2-4 Laps. Use you back and keep him behind. If he passes you, you have to restart. If at first you fail to keep him behind,he'll give you another chance when he finishes a lap.Good Luck!)

Then when you get ahead,he'll go slowly. Then speed up after a while. When he catches up to you,lean on the right side on the course. He'll bump into you. Try to keep him behind by staying on the right. Good Luck!)

Blinky

rive 99 Laps in Freerun Practice. Pick a very fast car on a short course like Ridge Racer Extreme. It takes time,but by the 99th lap,you should have the car even though the announcer doesn't say you did.
Red Shirt Rage:It took me tries for this one. Go to Class Z,Pick Ridge Racer Novice,and pick Ultra 64,Screamin' Eagle,or Crazy Canuck. Your goal is to hit the chopper. It sounds impossible for all couse and all cars exept this. Drive all the way to the brown curve at the end of the beach and watch to the right as the chopper moves down and to the left. Pick up full speed at it and it will stand close to the road. If you're fast enough,you should drive into it. The game doesn't tell you if you did it,but if you hear a crashing sound,Good Job! Finish the race and you should have it.
Crazy Canuck:This car is like Screamin' Eagle but it's Canadian and not U.S. Go back to Screamin' Eagle's Car attack. Turn around and drive into the wall. The course should go reverse. Crazy Canuck will take Screamin' Eagles place. It will follow it's every move. Just keep him behind by leaning on the left and you should win.
Caddy Car:In any race,turn around and drive into the wall. The course will be reversed. Catch up with your enemies and come in 1st. You should have it.
Pooka:Just set a new course record in Ridge Racer Extreme or Ridge Racer Extreme Extra and change your name when it tells you to. You should have the car even if the announcer says nothing about it. Just check in your garage.
