I’ll bet you one upvote, and I’ll pay it right now!

Exactly. Or, using the adaptive cruise control and lane keeping that many cars have these days. (Regular) Autopilot is becoming less of a unique feature of Teslas.

I would like to believe (but lack data to point to to support it) that ADAS is making roads safer overall. There are cases that aren’t covered yet, and driver complacency is a problem for those, but so is complacency in a driver’s belief that they can stare at a phone in their lap but not drift out of their lane and cause an accident, which is something ADAS will protect against.

Seeing an annular eclipse is an excellent application of orbital mechanics! Enjoy!

Drop a ball. It goes fastest just before and after it hits the ground, and slows down until it gets back to near the height you dropped it from

The probe is the ball, and slingshotting around the sun is like bouncing off the ground. The potential energy (height of ball/distance from sun) gets converted to and from kinetic energy (speed).

Salzburg, Mariazell (specifically hiking through Ötschergräben), and anywhere in the Austrian Alps are all excellent.
