Gallery I did get to test drive this Tesla Roadster -- all the torque all the time. This is what a half-dozen hot laps with Tony Stewart at the wheel will do to a girl. That's me in a helmet at Dover International Speedway. Those 200-mph race helmets squeeze your cheeks so everybody looks like a chipmunk. A badass chipmunk. The last in a line of collaborations between Mercedes-Benz and McLaren. With a car like this, it seems like it was a friendly breakup. NASCAR racer Tony Stewart is in the driver's seat, waiting for me to strap in.
