No way to answer. They are not equipped with blinker fluid systems. It is best explained here.

We may never agree on how many threads on a lug nut...
...but can we agree we are all nuts in this thread?

Yeah pretty much. Everyone likes a little fun on occasion.
To add some seriousness to this thread, the F1 people obviously have it figured out. The massive size of that threaded area easily withstands the load and with every tenth of a second (in the pits) equating to lots of distance on the track, they want that nut on and off as quickly as possible. More threads would require more time motionless.
As to the less fortunate us, we have to contend with a lot more threads (no pun intended - was referring to lug stud threads). I’m no engineer, but the stud is no stronger than its width and tensile strength. A lug nut twice as long as the studs width would certainly decrease the nuts ability to be “pulled” off of the stud, but IMHO no other benefit exists - Edit: Except for the softer alloy lug nuts which may benefit from additional threads.
If this thread was only intended for slapstick humor, my apologies for the serious input and please, feel free to continue with the silliness. I’m sure I’ll join in somewhere…

If you want to look at good design methods for bolted joints, I can recommend this book. Mr. Bickford is a clever man!
If I remember from my ME design days, most of the load of a properly torqued fastener is taken by the first thread and a half or two threads, as the stud will stretch slightly. This is the reason that if you plan to use a jam nut (1/2 thickness nut to lock a second nut), the jam nut should be applied first and then a full nut tightened to the jam nut. If you apply the jam nut second, it will take more of the tensile forces. The jam nuts are designed to take full load but there's no safety factor left.
Anyway, back to hookers and blow.......

Back to the original title, I believe there is 1 (one) thread on a lug nut. That was the original question, yes?
Just like there is 1 (one) grove on a 33&1/3 LP. 1 (one) song on an LP side (think 2112 or Close to the Edge) or 8 songs on an LP (anything Beatles, Dylan, etc.), still only 1 (one) groove. Same with a Lugnut.
Just one long thread/groove. Just 1 (one).
