I like the way our example driver runs a stop sign at 7:58 best, followed by the animated poor examples of squared and rounded L turns at 10:47. Seems to me "slow enough" would make the difference negligible.
I also thought they could have included road crowns and off-camber turns (where the road tilts to the outside of the curve) among the "Highway Factors", but I guess you can't cover everything.
Good poop, that's been repeated 1M+ times... I just wish I couldn't find some common traffic violation in it.
