Well, on the PS2 you hit L2/R2 to look left/right which is easy to do. PS2's buttons are closer, so holding X to drive (usually I'm coasting for drive bys anyway) and hitting O to fire is quite easy.
On xbox now you have to hit w/bl to look l/r AND hit A or B to fire. Quite a distance there. And of course to look back you have to hit bl + wh, which isn't easy on xbox, but is easy to hit L2 and R2 at the same time on the PS2.
The stick is friggin worthless as a camera. who cares? I wish they made it look like in hte double pack
