Via what method? Iirc, there are many economical methods of transportation between those two cities... Also, that $100 per hour is pure cost with no markups to provide for revenue or growth.
I could easily be wrong, but the aircraft they were displaying looked like a 2 seater, not 4.
WRT Caltrain, I remember using it for commuting, and certainly don't remember paying $50 a day to do so. But perhaps the times have changed and the prices with them. Still, $25 per ticket one way seems ridiculously high.
