John didn't mention it, but in the first game, you can actually unlock all of those filters and camera angles for play during the actual missions and not just for the replays. You have to beat the game on Hard with the Heavy Traffic setting (a daunting task).
It's a shame there's no free drive mode in the first game. Any exploration you want to do has to take place inside the mission time limits, which are generally in the 2-5 minute range.
Microsoft owns Activision now. Both of these games should be added to Backwards Compatibility.
