Forum:Vehicles loosing boost...(not a joke)

Hey guys. So, I've had this happen twice now. I join an online game and whenever I hop into a vehicle, the boost justs starts draining - I'm not hitting the button, and the vehicles not going any faster - THE BOOST JUST STARTS DRAINING FROM THE METER. When the other people in the game drove, they didn't have the problem... So what's going on?
