Then he estimated the probability that the same thing will happen when there are multiple successive traffic lights, as usual in the cities.\n>\n> The result is that as fast as an aggressive driver goes, **the presence of multiple traffic lights makes it virtually certain that a slower driver will catch up**\n>\n> So, if someone aggressively overcomes you, when you reach him at the next traffic light, you can tell him that it is _mathematically proven that he/she is an idiot._\n>\n> In addition, this study has implications for the 30 km/h city, demonstrating how in urban areas _the traffic lights determine the travel times_ , not the maximum speed reachable between one traffic light and the next.\n>\n> The original scientific article is here: royalsocietypublishing.org/…/The-Voorhees-law-of-…\n>\n> crossposted from: poliversity.it/users/…/116419204210303856",
