I pretty much gave up trying to scrape things after I reached puberty.
My morning route includes this steeply downhill bit of road.
That's pretty much it. No other sharp corners.
Tree-lined, winter shaded....for ice and/or wet leaves.
Had a moment one morning a few years ago - a very well driven 1st Gen. Golf GTi came upon me in these bends. My scooter tail lights surprised him in the dark, but he managed to pass me with inches to spare!
That bit of road in his morning commute is probably his favorite. Only a GTi could have accomplished his maneuver. (thank you Wolfsburg!)
