ah! of course.

With this approximation, riders would tend to maintain same position in tight corners, but then those on inside would have lower exit speed.

A heuristic approach is also possible, considering both.

I think I'd be tempted to calculate not a maximum speed, but a maximum rate of heading change sqrt(A/R) where R = centerline radius and A = effective traction limit, and scale speed to enforce that maximum. I think that would improve realism of pack dynamic.

Thanks -- that should have been clear to me from video, where riders on inside line are rapidly advancing in switchbacks. Simple physics is inside line makes faster progress (∝1/sqrt(R)) but requires more deceleration and acceleration, so is overall possibly slower. But then there's apexing...

Also, does auto-braking depend on the radius of the rider line, or the centerline?

Is that the Poggio descent?

compared to that, the earth is a nanoscale particle, and when it’s soon inhabitable, it will just be the smallest blip in the rise and fall of life in the universe.

That doesn’t help, however.

I’m an incurable optimist.

As an aside, Trump speaks at a 4th grade level (Factbase) and managed to get elected twice, so education is dead.

You obviously can't tell the difference between actual corruption and fabricated corruption. False equivalence is endemic.

He's an actual scientist. If he said something about AIDS transmission it was based on published results. And I very much doubt you are representing what he said accurately.

when the captain steers the boat hard towards the iceberg, one tends to lose interest in what’s happening at the sunny destination.

and how did that work out for them?

Bad example.
