From all the cities I've been to I can only remember 1 or 2 that approximately fit the description and then again, only at a certain time of the day. In most others, the goal of a public transit service is to get you to destination eventually.
Chicago buses are extremely punctual where I live (+/- 2 minutes) in river north. And of course in Manhattan it takes far longer to get anywhere by car than by subway, or even express bus.
