Slow cars in front of you are doing you a favour. Sure they can be a bit annoying when you’re trying to get somewhere, but they’ll only be in front of you for so long, and they help keep you in check.

This is easier to say in Japan where the speed limits are ridiculously slow, so if a car in front of you is going really slowly that might be a legitimate cause for concern, but I often think this when cars are going the actual limit. They aren’t doing anything wrong, it’s the speed limit that needs changing.

Either way, the metaphor sticks. These things can be seen as a way to pace yourself, to not get too far ahead of yourself, to stay grounded, and the stay steadily on course.
