If you think things can't get any shoddier, try calling up the PDA thing that stores maps, mission objectives and so on. It's an utterly diabolical creation that requires loads of counter-intuitive back and forth between screens.
For example, after you catch a criminal by bumping into his car three times you have to call the local cops to arrest him. Check the map screen for the nearest police station. Find the station's name on another screen. Memorise its phone number. Dial it on yet another screen… Wow. Impressively awful.
