Your use of the word incompetently makes it all seem so reasonable. If a small animal runs out (like a fox - very common to see these dead on UK motorways) human instinct (in some, at least) is to brake. The driver behind may remain mystified as to why that happened, if they never see the fox, which they might well not.
Incompetent sudden braking is possible, I expect, but exceedingly rare, and I’m still not sure it qualifies as an exception.
“Only a fool breaks the 2 second rule.”
(Which I am repurposing for current events: Only a fool breaks the 2 metre rule.)
A person I knew from my last workplace had 1998(?) Fiat Multipla where a torn alternator belt wrapped itself around crankshaft pulley in such a way that it stopped the engine nearly instantaneously, causing timing belt to slip and destroying engine.
I was going to crack a joke about buying a second toy version, but I can’t even afford the damn toy…
ETA:
You seem to be correct in general, but it seems that hypercar tuners often go rich simply to supply more fuel to the combustion chamber which actually causes the engine to run cooler overall. However, since they’re revving so high, the temp increases despite being a generally cooler mix. The result of the excess fuel is that unburnt fuel is exhausted and ignites in the exhaust. Apparently the Aventador has a serious issue with this due to the proximity of various other components being saturated in fuel, overheated, combusting and being in close proximity to flammable materials (this must be what @anon75430791’s buddy meant).
Having said that, I have no idea what I’m talking about; that’s just what I’ve just learned researching. Like home electrical work, I have avoided knowing too much about things I could really screw up or kill myself doing like the internal mechanics of an engine. I’ll change my brakes, but I’m not about to go into a carburetor.
There are a lot of crashes with brand-new high-performance sports cars because apparently drivers find the behavior of the vehicle - steering, accelerating, braking - to be completely different from what they’re used to. Cars with even slightly unusual pedal layouts cause people to (more frequently) mistake brakes with accelerators, causing accidents as well.
So it seems not-inconceivable that a new sports-car owner could end up switching from traveling at a high speed to braking when they didn’t intend to - or braking much harder than they intended to - causing an accident initiated by their own inability to competently control their vehicle. And yeah, people should be practicing defensive driving, but it can be somewhat difficult if someone changes speed in an unpredictable way or moves in front of you before slamming on the brakes. (Not that any of this is what necessarily happened in this case, which is why my comment was intended to be somewhat humorous.)
And the brake lights would come on, warning the driver behind. No idea if in this case the Lambo slowed/stopped with no brake lights (dead electrics?) or not.
Those were all off the shelf Hot Wheels (per the FAQ they can be modified just not for speed so repainting, decals etc are allowed) which can be had for $1 US give or take. I had one back in the 80s which I repainted and added lasers to for the GW game Dark Future. and it was an car from the local department store.
ETA the ones in your link are 1:18 scale so quite big and depending on dies, production runs, luxury markup those prices are not awful. More than I can afford. Bog standard Hot Wheels are 1:64 scale and much more fun.
Was the OP gentleman’s Lambo insured? Circa 1980 I encountered a USMC (that’s Marine Corps) fellow who re-enlisted for a large bonus, blew it on a top-of-the-line Jeep on Friday after local insurers closed, intended to buy insurance on Monday, but totaled it the Mohave Desert back-country on Sunday, during my ambulance shift. He wasn’t badly hurt except for a six year commitment with his bonus gone. Moral: Insure first.

Drive one for a while, they are simply amazing!
Love of exotics, beauty of the build, performance, symbolism of owning it
Access to ridiculous sums of cash. Some people can wreck an exotic and have a replacement within the same week just because in the time it takes to get the new one they have made 4 times the cars value in a divided payment.
