Pursuit Force: Extreme Justice hands-on at Gamespot.

"Pursuit Force for the PSP was met with mixed reactions when it launched last year. Its visuals were solid, the gameplay was fun, and it had some innovative features, such as the ability to commandeer other vehicles at speed. The latter was one of the better-thought-out dynamics--you could leap from your patrol car to your assailant's vehicle, kick him out, and then continue the chase without breaking pace. This became more than a one-off tactic and was used to huge success when your vehicle had taken one too many knocks, was about to blow up, and you needed a replacement. Unfortunately, one of the biggest criticisms from both reviewers and gamers of Pursuit Force was its difficulty level. The curve was steep, and left it sitting a couple of notches above challenging. You were forced to sit through the same cutscene over and over while you waited to retry that level you couldn't finish."
