Bicycle geometry update

Received this overnight:
https://cyclingmagazine.ca/sections/news/paths-unmanned-bicycles-pushed-fall/
Which seems to be 'simulated' data, not actual observation (although I think that does approximate reality pretty well.   then again I am not a physicist.)
Next, I'd like to see the plot of an actual riderless bicycle with 800 iterations to compare assumed paths to actual, just to tie things up a bit.
