A local train covers the same distance in 91 minutes (vs 81 minutes for this shuttle) but also makes every stop. A baby bullet train that makes roughly the same number of stops as the shuttle does the trip in 57 minutes.
Caltrain's baby bullet trains beat every other mode of transportation up and down the peninsula in terms of speed assuming you live by one of the stops AND the train isn't delayed due to the distressingly frequent accidents and mechanical failures.
Almost every mode. During traffic they certainly do although on my motorcycle with the power of lane splitting I can beat even the bullet (48 minutes) from mountain view to my office by about 8 minutes. Not including the 12 or so minute walk from 4th and king to work. And of course the baby bullet only operates at peak times.
In the middle of the night (like this service) perhaps not. I still like it though because parking is such a nightmare.
