220km driving with 1 wheel nut holding the front tyre on

By far the closest moment to an insane death.
I was driving back home from a long night of street drag racing at Shepparton in my 1985 Ford Fairmont XF Ghia.
On the way back to Wangaratta I reached speeds in excess of 200km.
A mate of mine insisted we take a lap of the main street before taking him home.
As we cruised the street he asked me what the banging noise was and after turning the cd player off I too could hear the noise and quickly pulled to the side of the road to investigate.
Immediately I thought it was the tailshaft but it was fine. So I rang my father, who prompted me to count the wheel nuts.
That was when I realised that the front passenger side wheel only had the small locking nut holding the wheel on!
Not only that but 2 of the studs that the nuts screw onto had completely snapped off altogether.
The reason the nuts came off was because I didn’t realise on alloy rims you have to really tighten them up. I was used to stock rims and they have locking nuts so it’s not a big problem.
