Adding some ambient traffic noises. I think they ended up being kind of hard to hear in the final product. Additionally, I used the Paulstretch effect to draw out the length of the engine rev so it doesn’t sound like it ends suddenly. For the music, traffic noises, and the engine rev, I used the Adjustable Fade effect (under the Effect menu) to make the sounds gradually fade. I set it to fade from 100% to 20-30%. The normal Fade Out effect makes it go from 100-0 I think, so I liked being able to control the rate of the fade.
