My wild idea is tire chains for bikes. I used to live in Minnesota, in
an apartment that was within bike distance to work. In the winter, I
couldn't bike in the snow. But there are dedicated bicyclists who might
like something like bike tire chains, to drive the bike in adverse
conditions.

The design is trivial, but I'd have to specify what chain, the "T"
connections, and some kind of connector that's got length compliance, to
accommodate variations in tire diameter and etc.

So, any suggestions on a specific chain, some kind of "T", and a
connector?

Thanks,

Simpler, pieces of small square tubing strapped to the tire with
zip-ties. Use those stainless zip-ties if you're feeling fancy, but the
basic black quality ones should be fine for a season and easy to cut off
at the end of the season. No need for any circumferential chains, since
the spokes will keep the zip ties from moving anywhere.

You are forgetting that the brakes still have to clamp the rim.

Not any more! They'll just have to get close to the chains, and BAM!
the wheel will be stopped.

Do you need to implement control loops in software?
