Gotta love how they think that thane is puncture proof 
It can get punctured and that is far from the first time I had to remove shards of glass or really sharp gravel? from my sleeves. I haven’t had any issues with thane wheels but when it is a thin layer of thane on top of something else it looses that puncture resistance. Likely even more so if on top of a soft object or if there is an air gap between the thane and hard surface.
As an idiot who will ride in the rain, I fully agree with you. Don’t ride in the rain. Even if you completely ignore/don’t care about injuries at all you still shouldn’t do it because roads are disgusting and when they’re wet all that nasty road gunk gets flung up onto you from your wheels.
