The universe according to MMM

[MultiMillionMiler]

They must have adjusted that to make it seem more compatible with today's society. There's no way a young teen can go as low as 7 hours consistently. And some of the younger kid sleep needs are a little high, I don't ever remember sleeping 12-13 hours when I was an elementary school kid (I'd be restless at 7 am sometimes) Kids ages 5-10 always complaining about bed times being too early, and teens being tired all the time, they've got something backward. From what I learned in my psychology classes and neuroscience textbooks, it usually doesn't even fall below 10 hours until around 18 ideally. Society should schedule things more heavily based on circadian sleep rhythms rather than meal times. So many days I don't even really get hungry until around 6 pm anyway, so I could easily do a day's work without food. My energy comes from sleep, not so much from food. And even the author of the small book: "Life lessons from a Brain Surgeon", admits that there's no good evidence that breakfast is an important meal and recommends skipping it every day, but emphasizes how important continuous sleep is. Maybe work days should run more from 11 am to 6 pm without a lunch hour, instead of 9-5, to allow more sleep.

If there's one thing MMM has in common with the rest of the forum, it's passing off his personal experiences as being absolute fact for everyone.

Well, even MMM is not perfect in defying every common approach!

I think we've reached the point where this is the norm, and it's actually a surprise to see another thread pop up.

[Max Rockatansky]

Imagine chugging along on Tioga Pass Road at 17 MPH.  And I thought 35 MPH on the Wawona Road was slow...

[Max Rockatansky]

Well the ticketing systems wouldn't trigger until 23 mph, so I'm giving a very generous enforcement leeway. Be thankful prime numbers are spread out.

I could always just remove my license plates and flip off the photo radar camera (like I once did a 1993 Camaro Z/28).  It's not as though the NPS regularly patrols much less likely cares about someone not having a plate on (California thing).

Lincoln Hwy
https://maps.app.goo.gl/s5hGphgkQFVh4YyL6

What a reckless roadway! Both cars are closing in on each other at over 150 mph if both are going the speed limit of 75-80mph! All one driver needs to do is accidentally drift 3 feet and they're both dead. Even with high visibility, you aren't going to be able to tell if the car is going to hit you at those speeds. Since there's no other poles in that region, the speed cameras would have to go right on the giant 67 mph speed limit signs (which would trigger at over 71 mph). Maybe even put a few highway patrol officers along this route. And I'm also being genius of recommending a fine of only $97 instead of $101, choosing the lower prime number around $100.

Sounds like someone isn't familiar with their Lincoln Highway history.  Have a look where the Lincoln Highway was through Bean Flat back during 1913:

Oh and I've amended my national speed limit guidelines for non-limited access routes:

11 mph in Parking Lots/Toll Plazas
17 mph in Cemeteries/Park Type "Roads"
37 mph on State Routes
47 mph on US Routes
67 mph on major cross-country Routes like US 50

Speed Cameras would trigger once you've exceeded the next prime number over each speed limit.

If you're curious about my speed limits for freeways and interstates, I would say the only options should be 75 mph, 80 mph, or 90 mph, with 120 mph/Unlimited on cross country x0 and x5 Interstates. Trucks would still be limited to a maximum of 90 mph.

So US 20 through downtown Waltham MA should be speed limit 67?

And US 30 & 40 will both be 11 and 67 mph at the same time?

I'm generally one to advocate for road diets and slowing the fuck down in built-up areas, but this is ridiculous. Park roads vary wildly in design and the appropriate speeds for Paradise Road at Mount Rainier versus Bryce Canyon Road are not going to be the same. How about we leave it to the professionals?

Conversely, the "only" speed limits suggested for freeways are far too high. Sure, I-80 in Nebraska would be a fine place for high limits, but in an urban or mountainous area you can forget about going above the current limits. Try doing Siskiyou Summit on I-5 at 90 mph, you'll fly off into a canyon.

With MMM's plans

Those should be 12.5, 19, 37, 47 and 68!

I must have missed it MMM, what is the prime number obsession all about?

[hotdogPi]

Dollar bills should also come in Prime denominations. 3s, 7s, and 997s.

I've thought about this, but with coins rather than bills. Using a base-36 system, with five coins, you can pay for anything up to 34 with three or fewer coins if those coins have values 1, 3, 8, 12, and 18, and x.35 would be very easy to make change for (pay the $1 and receive one of the smallest coins back).

1, 4, 6, 14, and 15 can get you slightly farther with "three coins only", but that set is a much weirder combination.

[SectorZ]

Because I don't see how speed limits based on even figures or multiples of 5 is any safer? Might as well use actually interesting numbers. Dollar bills should also come in Prime denominations. 3s, 7s, and 997s.

Why is a prime number "interesting", from a functional standpoint at least?

[Scott5114]

Dollar bills should also come in Prime denominations. 3s, 7s, and 997s.

Having worked with both cash and the General Public and seen people's brain explode when dealing with such exotic denominations as $2 and $50, I can assure you this is an incredibly bad idea.

Also keep in mind that institutions like banks and casinos tend to deal with bills in bricks and straps, and fractions thereof. If someone can't figure out what the dollar amount of 50 pieces of one them is instantly, it's a failed denomination. (This is part of the reason why $50s are less used than $100s.)

My mom's 1975 high school yearbook had a cover designed to look like a $75 bill. I always thought that would be a really funny idea to have in real life because of how unreasonable it was. Sometimes to kill time I would bring it up at work as a thought experiment. Pretty much all of my coworkers reacted with amused revulsion to the idea, usually pretending to count them out ("75-150-1...aaaaaa what comes next?") or imagining  how weird it would be to have a strap worth $7500.

TD Bank's ATMs give out 3 denominations of bills: $5's, $20's and $50's.  I find that interesting that they would give out $50's for the reasons you mentioned.  The machine even defaults to that on withdrawals of $200 and above, although the user can revise the selection to the denominations they want.

I guess this is some standard ATM dealing with 3 denominations. There are 5,10,20,50,100 ($1 are too small, $2 are exotic) - bank has to pick 3, and I saw some funny combinations as a result.  Can be different even across ATMs of same bank.
And if 50s are too difficult, how about 5s?

[Roadgeekteen]

No those 2 would obvious be the other way around, those were general guidelines. And of course all mountainous curves would have my proposed driver assist fans installed and speed ticketing cameras and lower limits on those specific curves. So that section of I-90 and the mountains of I-70 where the truck accident happened, would likely only be 37 or 47 mph.

Pretty useless guidelines I see

37 MPH is 59.5 km/h, rounding to 60. 47 MPH is 75.6 km/h, rounding to 75.
All that "prime" stuff is just a backdoor for metrication...

Maybe if the machines are different, or in a different setting (casinos would provide 20's, 50's and 100's). TD Bank appears to maintain a common denom distribution though with their machines

(yes, I know it's not an official sign)

[roadman65]

So they should post an 88 k/ph than 90 k/ph so it is equivalent to 55 mph?^^^^^

[MultiMillionMiler]

No, but a 109 km/h that also converts to around 67 mph.
