My pleasure! I was thinking, perhaps the player's car could be configurated by default to be unable to catch the yellow car due to speed, maneuverability, etc., so getting a few powerups would be required; in addition to the challenge of catching the yellow car, the player would be juggling how many powerups to get, which ones, and when to stop grabbing them. I believe right now you can fully avoid the powerups and catch up to the yellow car with some good driving, so I could imagine seeing the yellow car slowly pulling further ahead would give the player the motivation to swing to the side and grab a speed boost powerup to continue the pursuit. :)
