Grand Theft Auto: San Andreas/San Fierro Courier
Get on the Freeway motorcycle to start the mission. You are given a set of packages and a set of targets to "deliver" them to. Each target is a corona and you deliver the package the same way you would do a drive-by shooting. With each level your time limit increases as does the distance between targets.
You have some extra packages so you can miss a few shots without having to return to the Hippy Shopper. Alternatively you can run over a thrown-and-missed package to pick it up and deliver it again.
If your biking skill is high you shouldn't have any trouble completing this mission. If your bike starts to smoke you even have time to duck into a Pay-N-Spray.
Cash is rewarded based on time and leftover packages remaining after each level. Don't get off the bike or you'll end the challenge before completion!
After Level 4 the asset is unlocked, generating up to $2000 per day.
