Mello's pretty sure Matt would stick his head out the window like a dog or a child if he wasn't the one driving. As it is, he drives with the window rolled down and the A/C blasting, car freezing, and music going loud enough to blow out their eardrums. If you took a snapshot of the moment, Matt would look as calm as anything, like he could be going 30 MPH down a scenic path, cigarette held out the window and a little smile playing on his mouth.
In reality, a chronic speeder, Matt can't seem to go any slower than twenty-five-o, but regularly pushes one-ten on highways. First time Mello ever got in a car with him, he was half-convinced he was going to die. Matt drives like a crazy goddamn bastard, weaving between transports and motorcyclists like he wants to kill someone, singing along to the radio and smoking all the while.
The first time Mello ever rode shotgun to Matt, Matt turned to Mello and asked, "You okay? You look a little clammy, man." and the first time Mello ever drove Matt anywhere, Matt put his hand on Mello's knee and pushed until they were speeding well-over.
Matt has to have a special talent for evading police notice though. In all the time they've been back together, they've never once driven legally, yet Matt's only been pulled over twice. The first time he managed to spin a story about a pregnant girlfriend no one in their right mind would believe (even without Mello in the passenger seat, lips pink and puffy, throat covered in marks), and got off with a warning. The second he spun around mid-pursuit, and drove back onto the wrong side of the road, barely missing startled motorists until they lost the police and ditched the car. Mello almost strangled him the second his boots hit solid ground.
