Let me grab this occassion to draw attention to a lesser known feature of Citymapper (not everywhere alas): it can make a public transit plan augmented by a cab. This is something I have been doing without an app myself at my home city in a very clear demonstration of the "time is money" principle. This is one of the true differentiating capabilities between Citymapper, Moovit and Google Maps, otherwise they would be quite similar.
I actually hate that feature and can’t figure out how to turn it off. It thinks getting me within 1-2 miles of my destination and hailing a car is better than being on a train for 20% longer but being much closer to where I actually want to go. I outright stopped using the app because it’s too annoying to make sure the suggested route doesn’t involving getting off a train and catching a car.
