Where I live, I can either take the MUNI streetcar, or the BART subway. The BART is a further walk, but is generally reliable and comes quite often. On the other hand, the MUNI comes much more sporadically but is a very short walk. It became a ritual in our household to check both the BART status (did someone fall on the tracks?) and the MUNI departure estimation before leaving.
Something had to be done.
