I Need some help because I'm gonna smash the game if I don't calm down...I'm at Guardian Angels, and I'm fine to snipe everyone who's out to kill Diaz, but when I hop on the motorcycle I either crash, flip or the guy gets away. I've tried putting cars in the alleys to make it hard for him to drive (spent a lot of time doing that) but this didn't help...I've tried putting a car close to where the bike I'd need would be left, but I can't get off the bike, get in the car fast enough...suggestions ? Please?
