There was some interesting stuff in there. Not surprising that the engine had several flaws out of the gate, being developed so close to the last bankruptcy. The plastic parts sent me back to my old 1998 Oldsmobile Intrigue with the famous GM plastic intake. I guarantee you the engineers hate that stuff, but they're often squeezed for budget and make do with what they can, until the warranty calls start coming in, the bean-counters start panicking, and the engineers go back to said bean-counters and say, 'well, if we revise the engine (i.e., design it the way we wanted to the first time), we won't have that problem anymore'.
Side note: not crazy about this trend in AI-produced videos. It would seem that a human wrote at least some of the script and then had an AI bot read it. I had to laugh when the 'narrator' said the 'Pen Tester' engine without skipping a beat...
