Video people are talking about 8.6x its usual comments

Scott Manley checks the physics behind Tesla's rocket-car flip

His vacation interruption brings cold-gas propulsion, Knight Rider jokes and an unusually busy comment section together.

Scott Manley Story of October 19, 2026Trari Newsroom

Why this story? The video drew 4,119 comments in its first day, 8.6 times a normal first day on this channel (479).

Let's Talk About Tesla's Rocket Car.... Even Though I'm Supposed to be On Vacation

Things we can learn from the video

Press to jump

3:32Underbody fans and dynamic skirts create suction to increase the car's cornering grip.
4:48Cold gas thrusters draw from a high-pressure tank rather than burning rocket propellant.
8:05Rapid gas expansion causes extreme cooling, while stored energy limits how long the thrusters can operate.
12:40Manley breaks down the flip and considers whether the brief airborne maneuver qualifies as controlled flight.
15:42He argues that a specialized stunt car or an airplane makes more practical sense than combining both.

Scott Manley is outdoors at night, working with what he calls "a very limited light source," when his vacation becomes a rocket-science lesson. Tesla's Roadster demonstration has prompted requests for an explanation, and a car with thrusters is apparently enough to interrupt the break.

"When you put rockets in it, well that becomes more interesting," he says.

The response is more conversation than viewing surge: the video drew about 4,100 comments in its first day, nearly nine times Manley's usual volume, while views were ordinary for his channel. Viewers are imagining action-movie escapes, comparing the vehicle to a Kerbal Space Program creation and asking what happens when a thruster fails mid-maneuver.

Manley supplies the engineering underneath the spectacle. He explains that the car uses cold gas thrusters, releasing compressed gas rather than burning rocket propellant. That brings limitations: expanding gas cools sharply, and the pressure vessel holds only so much usable energy. Underbody fans and movable skirts provide a separate trick, creating suction to improve cornering grip.

The flip gets its own breakdown, including how the thruster arrangement controls the car's orientation. Manley distinguishes a brief airborne demonstration from something useful as a flying vehicle, ultimately making the case for a dedicated stunt car or an airplane instead.

There is also a very specific aesthetic objection: why wasn't it black, with the Knight Rider theme playing? The comments extend that thought into jokes about KITT needing time to recharge between jumps. Even on vacation, Manley has found a subject where television nostalgia and propulsion physics share the same road.

What viewers say

The hours to recharge is not an issue. KITT only needed this sort of thing maybe once per episode.

They're saying it's the most Kerbal vehicle ever built by non-Kerbals

(For better or for worse)

We did it guys. We have a gas-powered Tesla

This is so great! My city just replaced their HOV lanes with Hot Wheel tracks!!! Super excited, now
