Well christ on a stick, I feel I should print your post out and read it on the can to make sure I give it the attention it deserves. Dad always did his best reading when enthroned and I follow in his, er, footsteps.
I too have been on the road in snowy conditions. One could distantly argue it was reckless to boot - I was out solely as an excuse to be on the road in snowy conditions. It's difficult to find snow chains to fit my vehicle as there's not a big market for it, and currently the industry is heading towards the "weight weenie" goalpost, rather than concentrating on reliable machines. Anyone I took the first version of my home-made snow equipment for a careful, nay ginger, blast around the block. Upon return I realised that most of my efforts had been shed, so I had to backtrack on foot and undo my littering. Typical that all the parts I left in the white were...white.
Undeterred by this outcome - because science considers a fail to be winning - I decided to take the project to the next level, and headed to the local DIY outlet. On foot, I hasten to add. I don't want to risk killing myself before I get a chance to kill myself properly. I browse the available supplies in the store which will, in years to come, turn into a supermarket. I leave with a heavy rucksack of chains. I take steps away from the goal posts of so many of my kin. Weight bedamned.
Once I'm safely ensconced back indoors I begin the lashing and the first design used far too much chain, causing weight to genuinely be a problem. The rope I'd used to weave the chain around the wheels seemed redundant, too. Science once again triumphs in its failure and my second lacing method is much more efficient - a comparable surface area of chain with a fraction of the length of chain. I mirror my efforts to all of the wheels and venture out. I ventured out like a badass.
Those chains were quite a sight. And a sound. And they were actually pretty good! With noticeable traction on snow and ice I ventured out a few miles and came back with a plan. The plan was "This is brilliant, now I'll try it 250 miles away from home on uninhabited back roads by myself!"
