In a classic scene from Colt Breaks Out (Part 1), the unknown stuntman himself escapes the villains in an action set-piece very similar to KITT's turbo boost in Knight Rider. No copyright infringement intended.
Back in the good old days! Yes, a miniature truck and boat was used. You did what you had to with budgets. This was long before computer graphics and animation. The Fall Guy is a great all around family friendly series. I loved watching The Fall Guy!
