I understand the rationale of ATC for the Loupe One departure out of SJC for flights going north or east - to get them above inbound traffic to SFO and OAK. However, I wonder how much fuel is wasted every day with the departure to the north, turn back to the south, and finally turning back to the north to cross over the airport.

I appreciate how complicated it is to coordinate traffic among three airports, but I bet someday someone will come up with a better plan.
