And it’s a very weird and frightening feeling if I do get disoriented.
I know what you mean, there has been a couple of times in my life where my internal idea of direction has been turned off course and it is a very weird feeling indeed trying to reconcile the direction you internally believe you’re facing against the different direction a map or compass is telling you is actually true.
As a kid I also once spent a weekend in Melbourne feeling somewhat disconcerted due to not being able to get a sense of direction. I’d never been there before and flew in on an overcast day which never ended up letting up until I flew out so never ended up getting my bearings while we were down there (didn’t help that this was before the smartphone era so maps weren’t available at the drop of a hat).
Yes, while they look interesting there are reasons why saw blade lookalike wheels aren’t commonly used. I hate to think of how the weight of those dirt bike ones would affect the handling (probably not so much of a problem over smooth ice, but rougher terrain would be a challenge).
