This is the typical chase mission where you must pursuit a guy through traffic, which becomes very easy once you get to know the traffic and the route.
Now this mission also introduces you to Chop and how he can be useful sometimes, unfortunately the playing as Chop is limited to this and to "Predator" mission and what could have been a nice resource gets kind of forgotten.
Not training Chop or not keeping him happy will result on him not being obedient and this can make him behave bad, he won't bite, no but he won't listen to you either and if whistle at him there's a good chance that he won't give a damn. To train and keep chop happy you must download the "Ifruit" app to your cell phone though, as there's no in-game method to do this.
At the end of this mission you can keep Lamar's Speedo that has a unique license plate [LAMAR G], but since it's always available by going to a hang out meeting on foot or by taxi there's really no reason to save it in a garage.
