Human Factors
We were departing SJC via the RNAV Departure. We accelerated to 250 knots not realizing we were still below SFO Class B airspace. The Controller pointed out the speed below Class B. We reduced speed back to 200 knots until entering Class B. We attribute this oversight to a confusing clearance and quick turn of the aircraft before departure. We didn't take time to review overlying Class B airspace.
A corporate pilot reported exceeding 200 knots below Class B airspace.
