> OK. Drop 10 random points in a city and then map routes between them using transit, cars, and bikes. You'll find that cars are around 3 times _faster_ than anything else on average. Even in dense cities. I'm going to call this "Cyberax's constant"! From some level of experience doing just this all my life, this probably depends a lot on which city, how it's designed, and the time of day you do it at. There's some cities where you can actually get better results I'm sure! And there's some locations where I bet you'll get drastically worse results, especially during rush hour. I'm really curious where you're living at the moment! And have you considered making counterpoint videos vs NotJustBikes? ;-)

> From some level of experience doing just this all my life, this probably depends a lot on which city It doesn't depend on the city, if we're talking about cities with population more than 2 million! It's just the result of the inherent inflexibility of fixed routes. If you pick random points, most likely there won't be any direct route between them. So you'll have to do at least one transfer, and this just kills the average speed. That's why large cities tend to gravitate to the "hub-and-spokes" model. It's simply the only model that works. Look at the transit map for large cities: Tokyo, Berlin, Moscow, Beijing, and you'll start seeing it everywhere. BTW, it's also the reason bikes work well in Amsterdam. > And there's some locations where I bet you'll get drastically worse results, especially during rush hour. For this particular test, it actually doesn't matter that much, due to randomness of the chosen points. It's likely, that at least some routes will bypass the traffic magnets and chokepoints. > I'm really curious where you're living at the moment! And have you considered making counterpoint videos vs NotJustBikes? ;-) Yeah, I'm thinking about it.
