Un-rideable Bike?
Saw this youtube video by Veritasium last night about science of bikes, and how we adjust for turning subconsciously.
Interesting and also shows why we need more room from drivers on roads as we are constantly adjusting.

Radar tells me their closing speed, if they are slowing and how far away. Then I decide to say a prayer. The change of light pattern is incidental.

The place that makes me aware of it is my cycle lane that is where I turn left at a roundabout.
Being the traditional 18" wide cycle lane, (why would you need more, you've only got 25mm of rubber on the road) at a place where of course motorists need to use it to straight line the entry to the roundabout while my wheel wants to be very near the white line, as I want to maintain my speed from a downhill section. Many is the time a motorist is baffled at my obstreperous unwillingness to hug the kerb to avoid them and share the lane as any courteous motorist would do with theirs.
Bike stability science - according to this chap neither gyroscopic forces nor trail / castor effect are essential in keeping upright:

Maybe you just need to crash it first? http://bicycle.tudelft.nl/yellowbicycle/
If you were a bike geek this would seem to be an excellent job...
Nice! I do like a bit of bike science. Some more on counter-steering (for it is this) here:

More "bike psychology" - an engineer learns - then unleans - how to ride a backwards-steering bike:

Very interesting - thanks.
