I always wondered what the Spice Girls were singing about in that song.

Maybe the tunnel will be limited to electric ferries? This is Norway after all.

I don't think it is normal/usual for doctors to receive any benefits or profits from which drugs they prescribe. Other than golf outings with the drug company reps? Is there something I'm missing?

I suppose some of it is due to craigslist being around for 30+ years. At $25-$30 million a year, it adds up over time. And then if he invests most of it, 30 years of compounding interest does the rest.

I guess I'm not a traffic engineer. And there are of course humans-doing-crazy things. But the roundabouts in my neck of the woods are a lot more reasonable. Sure, there is the occasional timid driver who can temporarily gum up the work. I can't say I know if it is the drivers or the roundabout design, or what that would make roundabouts useful in some areas and less useful in others. I bet it would make a good YouTube video if someone were to critique one of the unsuccessful roundabouts (or at least I'd give it a click). And if someone is looking for YouTube video opportunities, it would also be interesting to see how Tesla FSD handles this. Line up 10 or 15 going in one direction, and another 1 or 2 in the perpendicular direction.

Has anyone done the YouTube research on what is the best way to bring down something like one of the Boston Dynamics robot dogs? 9x19? 00 buck? 5.56x45? 7.62x51? I suppose those bots would be pretty expensive, but maybe there is a cheaper Chinese knock-off? Seems like that sort of test would bring in plenty of clicks.

>If you pull in after the car already in the roundabout passes by, you get hit by the next one.

Yes, that seems like a roundabout design defect. Seems like the radius of the circle is too large, so cars aren't slowing down enough.

>From what I understand roundabouts make accident rate go up,

"Studies of intersections in the United States converted from traffic signals or stop signs to roundabouts have found reductions in injury crashes of 72%-80% and reductions in all crashes of 35%-47%"

I was surprised that the U.S. probably only has around 11,000 roundabouts. I thought it would be higher. If they were as popular as they are in my local area, there would be over 70,000 in the U.S.

>Constant traffic flow in one direction can make an entrance entirely unusable.

Seems like a poorly designed roundabout then. You should just pull into the roundabout, right after the car already in the roundabout passes by. Something is wrong if one direction of traffic can block the flow from other directions.
