Researchers in the Netherlands found that people perceived transit to take 2.3 times as long as driving a car. Your trip is actually much shorter than you think it is.

A recent study by researchers in the Netherlands put a number on it: when asked about how they get around, people perceived transit to take 2.3 times as long as driving a car. Interestingly, that number fell when the people surveyed habitually took transit in addition to driving - they were more familiar with what was involved and planned accordingly.

The perception principle also holds true for time people spend waiting for transit as opposed to being on it: a continuous ride will be perceived as taking less time than one that involves transfers and waiting, even if the second trip is actually shorter. Federal transit planners estimate that penalty to be somewhere between two and three times the actual time - so, a wait time of 10 minutes is perceived as 20-30 minutes.
