Depends on what car you're in and who you're trying to slip stream, I've got the trophy for spending at least 10 minutes slipstreaming so clearly it does work.
There is a bug in that slip streaming does not work if you are playing with a wheel. The work around (as strange as it seems) is that if you set a deadzone in your brake pedal to 2% (or more) it will then work.

I can confirm this works for most people! (Actually I was the one who found the solution first I think - Im Polemark at the CM forum. So proud I actually contributed with something for once, lol )
I'm always slipstreaming and it's fun. But I turn my DRS on, press the KERS button and plus slipstream I hit the rev limiter way too early so I get pissed off.
