knight rider online

Imagine they had season 8 (the final season) of knight rider, here's how it would end

Garth knight returns from the dead and so does KARR and both of them finally dueling out with KITT and Michael Knight.
and Michael Knight and KITT won the battle and garth and karr exploded.

Michael Knight retires from FLAG after 8 years of service and KITT 2.0 (1987 Pontiac Firebird trans-am) got decommissioned

(KITT's voice)
"this is the final cruise of KITT under michael knight's command, this car and it's history will continue to be a voyage of another person, to that one and their prosperity that we will commit our future, KITT will continue the voyage that it has begun and journey to fighting crime and criminals who operate above the law, because one man and one person can truly make a difference.

And, here I figured it would be Michael retiring from the Foundation, buying a beach side home and taking a hobby as a lifeguard with ownership over one of the world's very few cars that could drive on water.

I remember the baywatch episode where an suv drove on water and was robbing boats at sea. At the end of the episode Mitch says only thing this car can't do is talk.
