There may be more of these in time, but here's the first. Named urban ski 2 for no raisen.

So, you have to ski down the San Francisco esque street, and over a ramp to avoid to cars at an intersection. Then land your jump, speed down another slope and try to avoid 2 more cars at the T junction. The mod uses triggers, so the first player to touch the grass at the bottom of the hill with their hands wins (online only).
