Maybe it's just me, but it seems that if the bug is traveling slower
than the car (1 cm/sec vs 1 m/sec) and the bug does not start our
ahead of the car (the bug is initially at the wall), then the bug can
never catch up with the car.

I'm assuming there's some catch to the problem, like the car goes
around the world and comes back to catch up with the bug ("laps" the
bug, so to speak) or the bug travels in the opposite direction than
the car. But then you run into complications like the fact that the
car would have to be able to drive around the world or the car or bug
would have to go through the wall, etc.
