2) Police officer hides, catches unsuspecting driver speeding, stops driver, issues summons.

This is the very best approach. It's got the perfect tension leading to the greatest safety.

When you're expecting such an ambush (getting caught a few times will teach you to do that), and you're really paying attention and playing "spot the ambush" then they won't catch you. But because you're being so damned focused and alert, you're also a safer driver.

OTOH if they nail you, that means you weren't paying attention. So you weren't merely speeding; you really literally were speeding unsafely, and the ticket is the proof. (If you were so safe, then how come you didn't see the guy with the radar gun in time?)

Every. Single. Time. I got ticketed, my mind was wandering and not fully focused on the road. I wasn't looking for a speed trap, so I didn't see it in time. Busted. And those times I was looking? I didn't fall for it. I slowed down and avoided a ticket.

The ideal system (in terms of safety) happens to also be downright sporting! The ol' classic speed trap was almost .. a game?

To what are you alluding?

Damn! My mod points expired through disuse some time over the last 5-6 hours.

My Kilimanjaro suggestion was aimed at people who had always planned to turn back long before getting anywhere near the top, and I felt the need to point out that 3000m is not a big deal for most people.
I'm not a mountain climber, although I'll walk or ski at those altitudes without a second thought, although ski touring (walking uphill through deep snow with "skins" on my skis) is not something I'm planning to do again at my age.

I believe "Y'all aren't ready for that" was her response when asked if she would run for president.

They make household filters specifically designed for microplastics now. I don't know how well they actually work.

Sure, but can you go "Berlin to Warsaw in one tank" using renewables?

TDS stands for "Tiny Dick Syndrome"... right?

Obviously, to go to 100% renewables we need a grid upgrade and far more energy storage. Sodium batteries look promising for that, but they need to ramp up production enough to drive the per-unit cost down.

I wonder if anybody regrets buying those big diesel bubba trucks to coal roll the Teslas with now...

Trump wants all the wind turbines and solar panels torn down, so we can use more "beautiful clean coal"!

People used to complain that my Setter was too skinny, even though she had unlimited kibble supply from a 2 gallon dispenser. I figured out years later when I found one of her teeth on the floor that she had abscesses on her teeth, which likely made it hurt to eat kibble. But she never complained about it, so I never knew. Turns out I should have been spending the money for wet food. I miss that dog, she only lived for 12 years.

I'll stick to the GLP-1, thank you very much. I started taking it for Type 2 Diabetes and lost a lot more weight than i wanted to.

I don't want to kink shame anyone, but maybe you should keep your fetishes to yourself!

Dude! Artemis could have used your help on their toilet! You seem to spend a lot of time thinking about how to clean up bodily fluids in zero-g.
