One major concern is that San Francisco's network of buses, trolleys, cable cars and streetcars is not dependable or robust enough for commuters to leave their cars behind. Bent said the tolls would net between $35 million and $65 million annually, money that would be used to improve transit service.
But that is far from the only complaint.
David Milner, an engineer who attended the first public hearing this month, lives half a block outside one proposed zone. To get to his job in Mountain View, an hour away, he would have to cross into the toll area. Public transit would more than double his commute time.
"What the city is going to do is charge me to get on the freeway to get out of the city," he said. "The route I take, there's zero congestion . . . If I went every day, that's $1,500 a year. That's just absurd."
Jim Lazarus, senior vice president of the San Francisco Chamber of Commerce, told the authority at its Dec. 16 meeting that people outside of the city will make "decisions based on these costs," and business will be driven away.
