This is asymptotically true for high speeds but false for low speeds where 2-seconds-car is comparable to the average length of a vehicle.
If the speed limit was (magically) 0.001 mph then raising it to 0.002 mph would double throughput.
- alexfoo 3y agoBut 20mph is not low enough for that to be a problem. 2 seconds at 20mph is ~18m.
- afiori 3y agoIt is not an overwhelming factor but if for example you were to go from 20mph to 10mph you would see an effect. Overrall lower speed limits (when streets are designed to take advantage of them) have a lot of benefits, this is in the category of minor drawbacks.
