The ambulance, however, is moving toward you - and so the point of emanation for the wave is piling up on itself, making the waves ahead tighter, and making the waves behind looser.
Just like if I walked toward you making waves in a pool. If I push a ball down into the water every second while stationary, you'll see the uniform wave. If I push the ball down every second while moving forward a foot every second, you'll see the leading edge pile up and the trailing edge spread out.
I think I got it. It really is about proximity. The closer the wave gets to something, the more jammed up it becomes. Correct me if I am wrong, but would it be wrong to equate that to a ocean wave building up and gettign bigger closer to the shore?
