They race past an oncoming car and now KITT and Michael are behind. Oh no! Michael orders KITT to switch to Attack Mode, which means that he'll go faster but look slightly sillier. KITT doesn't want to risk exposure, which is something he should have thought of last week, when he was zooming all over a city at 377 mph while on fire. So KITT flips to attack mode, gaining a spoiler and one of those engines that pokes through the hood. They catch up with Chang, but now there's an SUV sticking into the road. There's no way to avoid impact, except for turbo boost, which is naturally what they use.
While KITT is in the air, a kid in the SUV looks up through the sun roof and says "Sweet." For some reason, this freaks Michael out, so he says, "KITT, they can't see you like this. "Transforming midair could affect my structural integrity," responds KITT. Michael snaps, "We don't have a choice!" Reluctantly, KITT answers, "Transforming now." Okay, that whole conversation took place in midair, right? So they were up there for around 15 seconds, which is longer than the Wright brothers' first flight. And Michael thinks they'll be more inconspicuous if they change forms while flying through the air like that? Really? Maybe KITT's dialogue just takes zero time. That would help explain the line "Based on speed and trajectory, there is no way to avoid impact with the vehicle we are rapidly approaching," which was an obvious lie. It only took up one lane, and KITT started talking well before they would have needed to swerve.
Sorry. Sometimes the complete incomprehensibility of this show bothers me a little. While I was doing all that complaining, KITT blew out a tire due to all that structural instability he was talking about. Then Ian Chang slammed his convertible into a truck for no reason. Then Ian ran away just before the convertible exploded, which I guess has something to do with the fancy jet engine or something. Oh, and KITT has shut down. Credits! Finally!
