Street Hawk was a poor attempt at bettering the success of Knight Rider. I don't usually like highlighting failures, but I believe on this occasion it's necessary.
Whereas Knight Rider featured a car, Street Hawk was a motorbike. Both vehicles had onboard computers, both could do things normal vehicles couldn't do, both were set in the future, but only one featured a heavily permed David Hasslehoff. I believe it to be this last point that was the decider.
Had Street Hawk featured a perm, maybe I would have liked it more. As it was, it was only a programme about a man who drove a bike really fast through some streets and combatted crime.
I did like the first episode though, where they made Street Hawk's driver get fitted for a suit, and they encased him in foam for a few hours. That was cool I suppose.
