The cashless Golden Gate Bridge is another problem zone.

SF sues Hertz for "gouging" renters

The charges include a $4.95-a-day “convenience fee,” up to a maximum of $24.75, plus all incurred tolls, assessed at non-discounted rates. A single bridge crossing by Hertz customers triggers the convenience fee charges for the duration of the rental whether or not another toll is incurred.

Golden Gate Bridge officials are aware that its lack of toll collectors can confuse rental car drivers. The bridge district has pages on its websites explaining how car rental toll programs work and how drivers can pay tolls in advance or up to two days after crossing the span online, by phone or at cash payment locations. Paying that way avoids Plate Pass charges. But it’s up to drivers to discover that on their own.
