Why is the "Chase the gunman" mission so difficult???

[tjnk24]

The gunman's car drives like a tank, it's impossible to hit it, it's impossible to catch up, me and my friend spent about two hours just on this mission, and neither of us managed to pass it. I guess we're not the only ones who couldn't get through it. It's impossible.

Please MAKE THE GUNMAN'S CAR SLOWER, otherwise the game becomes impossible for the average person. This is not what was the in the original Driver 2 game.
