A battle has been brewing in San Francisco over driverless cars. Hundreds of the autonomous vehicles have been roaming city streets over the past couple of years and on Thursday, California's transportation regulator will decide whether to allow even more on the road.

San Francisco's police and fire departments are urging the regulator to say no – they say they've tallied 55 incidents where self-driving cars have impeded rescue operations in just the last six months. The incidents include running through yellow emergency tape, blocking firehouse driveways and refusing to move for first responders.

"Our folks cannot be paying attention to an autonomous vehicle when we've got ladders to throw," San Francisco Fire Chief Jeanine Nicholson said Monday in a public meeting about the issue. "I am not anti-technology, I am pro-safety."

The autonomous vehicles are run by Cruise, which is owned by General Motors, and Waymo, which is owned by Google parent Alphabet. Some of the cars have human safety drivers, others are completely empty. Select passengers can hail rides with the vehicles, like a taxi.

Waymo says it has a permit for 250 vehicles and it deploys around 100 at any given time. Cruise says it runs 100 cars in San Francisco during the day and 300 at night. During a July earnings call, Cruise CEO Kyle Vogt said the city could handle several thousand more driverless cars.

Both companies have urged the California Public Utilities Commission, CPUC, to allow for more cars and at all times of the day. They're also asking to deploy more vehicles in other California cities, including Los Angeles and Santa Monica.

The companies say driverless vehicles are safer than human-driven ones when it comes to passenger safety and that none of the incidents cited by the fire and police departments have resulted in passenger injury. Neither company has directly answered why their technology is responding to emergency vehicles this way.

"We have demonstrated our deep willingness and longtime commitment to work in partnership with California state, SF city and first responders," said Waymo spokesperson Katherine Barna. Cruise spokesperson Drew Pusateri said: "Autonomous vehicles are used by thousands of California residents and have a strong safety record."

Fire Chief Nicholson said that when the driverless cars get in the way of and slow down emergency vehicles, they pose a threat to public safety.

"Every second can make a difference. A fire can double is size in one minute," she said during the meeting. "If we are blocked by an autonomous vehicle that could lead to more harm to the people in that building, to the housing overall and to my first responders."

The fire department has also documented driverless cars rolling over the firehoses used to put out blazes. In one of those episodes, captured on police body camera footage obtained by Mission Local, a driverless car approached the scene of a massive fire in a residential neighborhood and inched slowly toward the firehose as frustrated first responders did all they could to stop it.

"No! Go back!" they yelled. "It doesn't know what to do!"

Several police officer and firefighter associations and unions in the Bay Area have written letters to the California Public Utilities Commission urging the regulator to hold off on allowing more driverless cars on the road, according to Mission Local.

"While we all applaud the advancements in technology, we must not be in such a rush that we forget the human element and the effects such technology unchecked can create dangerous situations," wrote the San Francisco Police Officers Association in June. The groups asked the Commission "not to approve the application for autonomous vehicles until more research is done."

Hundreds of California residents have also submitted public comments to the regulator. The vast majority say they oppose adding more driverless cars to San Francisco's streets. Many of the commenters quoted the words of Fire Chief Nicholson when she told the LA Times in June that driverless cars are "not ready for prime time."
