In a Hurry?

So today I was driving to a meeting, and part of my route was along a residential street that turns into a county road. The speed limit is 25 inside the town limits and increases to 45 once beyond them.

As I drove from town to the country, a truck followed me and in fact sped past me to head along the same road I was traveling. I, apparently, didn't go from 25 to 45 quickly enough.

I pulled into the same destination 45 seconds after the truck did.
