Some very normal person is gonna comment on this somewhere openly fantasizing about running all of them over for "taking up the roadway" and a bunch of other very normal people are gonna concur without any pushback.

Autobahn? More like Auto Ban!
highest throughput that highway has ever seen
- Looks to be an average of 2 ppl per lane with 3m ahead & behind. An average biking speed for commuters is 18-29kph, so let's do the calculus for 20, 25, & 30. This gives a throughput of 2x3x(20 or 25 or 30)/(3.6x6) ≈ (5.5 or 7 or 8.3) ppl/second
  
  Car occupancy is ~1.5ppl/car in the EU. Given that this is a german highway Average distance between cars ~3 lengths meaning 4x4.5m=18m/car. For a long time these roads had "no speed limit", but the recommendation was ~130kph. Let's conservatively use 120 & 100kph. This gives 1.5x3x(100 or 120)/(3.6x18) ≈ (7 or 8.3) ppl/second.
  
  Various things fudge the numbers in either direction, but that's actually shockingly close between the two.
  
  You don't enter or exit at 120kph so throughput is cut by the bottle neck of exiting/entering (also the reason why there's traffic no matter the number of lanes, bottleneck is the throughput of entry exit creates the traffic stall
  
  I gotta take issue with those numbers. A car moving at 130kph covers 18 meters in about half a second. According to the numbers I found online, experts estimate the perception-reaction time for braking at 1.5 seconds, which is up from the value of 0.75 seconds that they used to use. Thirteen and a half meters is an unrealistically-close following distance, even for German super-humans.
  
  I have not driven on the Autobahn, but the videos I can find show scenes much more consistent with a ~55 meter (1.5 seconds) gap between cars, or much-slower traffic speeds. That drops the estimated human-throughput way, way down.
  
  Here is some data to get more accurate numbers:
  
  max speed on that highway for cars is 80km/h
  
  the bicycles had an average speed of ~18km/h
  
  Ok, but still healthier for all.
  
  And you can savely take half of car throughput on average. Or far less in congestion.
  
  They did the math lol
Can we please get a comparison pic of 32,000 cars on the autobahn?
- You need a satellite to do that, I think
- Wouldn’t it be better to compare 32,000 people in vehicles? Doing really rough math, someone else who doesn’t suck at math should run through it lol. But hand jamming some numbers gives me a bit over 20 miles (32.5 Km) of flowing, 3 lane, 4 person cars to get to 32,000 people. It’s like 9 miles (14.5 Km) with bumper to bumper LA stopped traffic. 50 person buses, bumper to bumper is 1.8 miles (2.9 Km).

  32000 people in cars ≈ 32000 cars

  Okay, okay, so it's not literally 1 person per car and is actually more like 1.2 in Germany (see fig. 3) -- but it rounds down!
  
  Not exactly what you asked for but still a good visualisation
  
  Yeah, probably. But way too many cars are single occupant at any given time.
And one rollerblader
- That's Gerry. He's cool.
I don't want to annoy you, but imgur blocks VPN-access, so please try to use other services.
- yeah i know, sorry about that :P i was using boost to post this and didn't know it would automatically host it using imgur
  
  any recommendations for alternatives these days? i would've gone for something like catbox.moe or 0x0.st but I think those delete uploads after a certain amount of time
  
  How long does Catbox keep files for?
  
  Forever. If you don't want your file to stick around until the heat death of the universe, use Litterbox.

fahr'n, fahr'n, fahr'n, auf der Autobahn.
- Does "fahren" apply here? The German word for bicycle is based on the same word, if I am not mistaken, so probably yes.
  
  @daddy32 yes, fahren means to ride any sort of vehicle.
beautiful 🌟

and fuck cars btw...
Yeah it was nice. I didn't do the highway route because the kid wanted the child-friendly part, but still it was really nice to see so many people in the streets.

There were people coming from other cities as well, riding the whole night to get to Berlin on Sunday. Love it.

By the way, 32k sounds a lot, but in its heyday there were 200k people riding around. Even last year with 50k crowd it was completely different feeling, the inner city almost without cars.
