The Tenth Doctor makes me think of Richard Hammond of Top Gear fame.
Maybe I spend a little too much time following motorsports?
(Randomly, I just realized that I don't know when my favorite codriver's birthday is. WRC.com says that it's 8/30; Wikipedia says 8/20. Given how reliable WRC.com can fail to be, I'm tempted to believe Wikipedia. Must write in and bug the WRR folks after the summer break.)
