We have original Knight Rider here... https://www.tvmaze.com/shows/825/knight-rider
And we have Knight Rider from 2008 here... https://www.tvmaze.com/shows/451/knight-rider
The 2008 series are marked as "Reboot" but aren't they direct sequel to the original Knight Rider?
In the pilot episode there is David Hasselhof who plays the same character from the original which indicates this is some sort of continuation.
Also, while wikipedia isn't really a trustworthy source, they mention this under Knight Rider (2008) TV film (which was pilot to the 2008 TV series)... ***Knight Rider is a 2008 television film which was created to serve as a backdoor pilot for the new Knight Rider television series, and aired on February 17, 2008. The serves as a direct sequel to the original series and ignores the Knight Rider 2000 film and the Team Knight Rider television series.***
