In Pixley, Tom was still with the mare.

Mare: Are there other ponies trying to get that promotion like you?
Tom: Yes, but I'm in front of them all. We have just over 100 hours to get into Seattle, and I'm going to make it before anypony else does.
Karl: *Driving his car when he sees a black Cadilliac* Could it be? That might be Tom. I better floor it before he catches up. *Floors it*
Mare: *Sees Karl going faster* What's with that guy?
Tom: How should I know? I never saw that pony.
Mare: Let's find out. Speed up.
Tom: *Goes faster*
Karl: *Sees Tom catching up* Oh dear.
Tom: Getting closer....
