If tomorrow we banned non-self-driving (NSD) cars, sure. But in most countries, grandfathering in old cars is going to happen for a while. Which means that self-driving and non-self-driving cars will have to share the road.

I could see some transitions possibly. For example, on a 4-lane highway: "In 2027, lane 1 will be separated by a barrier and only allow SD cars. Lanes 2-4 will be for NSD cars only. In 2029, lanes 1-2 for SD. By 2033, NSD cars will be banned on this highway."

Is that Ace Ventura in there?

What YEAR is it? My 10-year-old self would be so excited for this

Yes, there's a bit of a myth around Bernoulli's principle (faster moving fluids have lower pressure) and how much it matters for lift in plane wings. It came up in the conversation because I was trying to describe what air pressure is in general, and made an analogy to a pan flute (he plays flute in band).

Disclaimer: I'm an aerospace engineer, but I do not claim to be an expert on topic.

But for plane wings, the myth is really that the air above the wing moves faster because the curved surface is longer. That's pretty much dead wrong, but is still in tons of textbooks. The air above the wing does move faster, but it's because of a bunch of complicated physics that to be honest, I don't really understand any more. I may have even been taught wrongly in college. But the result is that there is a velocity difference on a cambered wing even when it's flat, and thus Bernoulli's principle does apply, and there is a pressure difference giving you lift.

But that speed difference is mostly important at cruising altitude, when the wings aren't angled, and it's positively correlated with airspeed, so the thrust matters way more. When you're climbing, the angle matters more. The camber (curvature) of the wing, the airspeed, and the angle of attack all lead to that pressure difference, along with a few other things like circulation, which is also caused by a sharp edge at the back of the wing. But everything kind of works together to generate that pressure difference and hence the lift that can combat gravity. It's actually pretty hard to try and dumb it down without saying things that aren't wrong.

I recently taught my 11-year-old nephew "how planes fly." A bit oversimplified, of course, but words like camber and lift and circulation were tossed around along with Bernoulli's principle.

I pay for MLB TV, because I live in a different media market than my favorite team. So it works perfectly! Unless I'm visiting my parents. Or often when I'm traveling. Or is the game is on cable. Or the weird exclusive games like Apple TV. Or if it's the playoffs. Or because the chemtrails are too thick that day so the lizard people are out. But works perfectly!

Seriously, though, MLB does work pretty well and I do like some features (syncing radio broadcast with the TV, condensed games if I missed one). But it's very weird that most of my family who lives within 20 miles of the stadium can't watch the team when I live hundreds of miles away and can.

Maybe he just likes summer breaks as well. Then he gets back in the fall, and is all like "oh shit I need a new plan to kill that kid, uh...maybe I can send a man rat to sleep with his best friend? It'll take me at least until the spring to get that going, though."

I think that's also the problem today, albeit of a different sort. I had a friend who was very seriously into the "punch Nazis" meme on the internet a few years ago. But he would often talk to us about it and finding someone to punch. He sometimes said shit like "I could just go to the Republican national convention and start punching people."

If it floats your boat, punch Nazis. But don't punch everybody you disagree with because "not supporting universal healthcare" is not being a Nazi.

It's just an homage to Trump, who is famous for not paying bills!

Calvin dated Susie in high school, but it just never worked out. He and Moe met up in their twenties at a music festival and ended up reconnecting after Moe apologized, admitting that he had bullied Calvin because he was insecure about how confident he had seemed back then. They had both come out after high school, and ended up dating, getting married after a few years. This scene depicts their oldest of three children, Hume.

Because people are rarely single issue voters. There are a few here and there, but given the dominance of the US's two-party system, you often have to make a choice. If I imagine 2 candidates: one who is strongly pro-choice but overtly anti-gay, and another who is strongly pro-life but also pro-LGBTQ issues, that would actually be a pretty tough decision for me.

As much as I want to hate Trump supporters, I can still sympathize with them. A lot are lifelong Republicans who are choosing between someone who will probably try to enact 90% of their personal beliefs but is an authoritarian crazy person, and someone who seems sane but disagrees with them on 90% of issues and will do everything to stymie the things they believe to be right. It's not a simple choice.

I'm ignoring third-parties here as a caveat, so apologies if that's the crux of your question. But my opinion is that you should push for and vote for a new system while accepting that the rules are what they are now, and you have to strategize with the current situation.
