      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.

        Ok, but still healthier for all.

        And you can savely take half of car throughput on average. Or far less in congestion.

          Just a fun calculation, aiming at comparing the video to a reasonable max throughput of people in cars that may have ocurred, not the average :)

        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
