Knight Rider's Full 90-Episode Run Is Free to Stream Again, and KITT Doesn't Look So Fictional Anymore

My flatmate sent me a screenshot last week of a talking car's dashboard and the caption "why is this free." She meant Knight Rider, and she was right to ask, because for a while the only legal way to watch all 90 episodes was to buy the DVDs or pay per season on Amazon.

That changed sometime this year. All four seasons of the 1982 to 1986 NBC series, David Hasselhoff's turn as drifter-turned-crimefighter Michael Knight and his AI-voiced Trans Am, are now sitting free with ads on both Tubi and The Roku Channel, confirmed live on both platforms as of this week via JustWatch.

A show about a talking self-driving car, watched on a service run by a talking algorithm

Here's the part that actually makes this worth writing about instead of just noting in passing. KITT, voiced by William Daniels, was pitched to 1982 audiences as science fiction: a car that talks back, scans a crime scene, and mostly drives itself while Michael Knight leans back and lets it. Roughly forty years later, voice assistants, adaptive cruise control, and cars that genuinely can parallel park themselves are default features on a mid-range trim, not movie magic.

Softonic's own writeup leaned into exactly this, pointing out that "KITT's voice replies, directions, phone calls, scanning tools, diagnostics, links to wearable tech, and the overlap with self-driving technology don't feel like pure sci-fi anymore." That's not a stretch. It's the same gap that makes old Star Trek communicators look like a flip phone ad now: fiction stops being fiction, and the show either ages into camp or ages into something closer to a prediction. Knight Rider has landed somewhere in between, which is probably why it keeps getting rediscovered instead of forgotten.

The reboot machine is already circling

The free-streaming timing lines up with real studio interest, not just a nostalgia algorithm surfacing an old title. In August 2025, The Hollywood Reporter reported that Universal is developing a Knight Rider feature with Jon Hurwitz, Hayden Schlossberg, and Josh Heald, the trio behind Cobra Kai, attached to write and possibly direct, with David Leitch producing through 87North. The project was described as early-stage then and no cast or release window has been announced since.

That's worth flagging plainly: a movie in early development is not a confirmed release, and nothing ties the streaming availability directly to the reboot news. There's no press release from Tubi or Roku naming Knight Rider a strategic acquisition tied to the film. What's true is narrower and still interesting: the same year a studio quietly starts building a new version, the old version becomes easier to watch for free than it's been in years, and that overlap is doing real work in why people are noticing the show again right now.

• Original run: September 26, 1982 to April 4, 1986, NBC, created by Glen A. Larson.
• 90 episodes across 4 seasons, currently free with ads on Tubi and The Roku Channel.
• David Hasselhoff played Michael Knight; William Daniels voiced KITT without ever appearing on screen.
• A Knight Rider movie is in early development at Universal from the Cobra Kai writing team, first reported August 2025.

Worth knowing before you binge all four seasons

A caveat, because I'd want it if I were reading this instead of writing it: quality drops off noticeably by season 4, when Rebecca Holden and Patricia McPherson had cycled out and NBC was clearly trimming the budget before cancellation. If you're doing this for the nostalgia, seasons 1 and 2 are the ones people actually mean when they say Knight Rider held up. Season 4 is for completionists.

Ad-supported free tiers like Tubi and The Roku Channel have made this kind of resurfacing common: a title too old for prestige-streamer real estate but too well-known to disappear finds a second life where the only cost is a mid-episode car insurance ad, which, watching Michael Knight talk to his car, is genuinely a little on the nose.
