Bay Area teenager fails driving test due to Tesla’s regenerative braking system


GILROY, Calif .– After an examiner failed a teenager driving a Tesla because of its unique braking system, the California Department of Motor Vehicles asked its staff to treat electric vehicles the same as gasoline vehicles conventional during – wheel drive tests.

The communication to agency employees follows a driving test on November 23 at the Gilroy office.

Bryce Rosenblum, 16, began his driving test alongside the DMV monitor in a Tesla Model 3, with regenerative braking activated in standard mode.

“Right away, she warned me that the car was slowing down on its own, like at a stop sign,” he explained. “She told me that this had happened twice, before we even left the parking lot, then we continued the test. We did everything a test is supposed to contain, then she pulled me in and told me that I had failed. “

The regenerative braking system on the Model 3, like most electric vehicles, activates when the driver releases pressure on the accelerator. The system then recovers kinetic energy from the vehicle and charges the battery, slowing the vehicle without using the brakes.

According to the teenager, the instructor at the DMV did not order him to deactivate the regenerative braking system.

In the comments section of the driving test results sheet, the instructor wrote: “The applicant did not slow down the car. Did not put his foot on the brake until after the car had slowed down and stopped. “

“And so I asked her what I could do next time to pass the test, and she told me not to take a Tesla and just borrow someone else’s car,” said Rosenblum. “Bring someone else who has an engine instead of a real electric car.”

Bryce’s father, Neal Rosenblum, filed a complaint with the local office and referred the matter to the supervisor and the regional manager. The father recalled a conversation with the instructor immediately after the test failed.

“It’s an interrupted process,” said Neal Rosenblum. “Essentially, she was saying the car was braking on its own. And I said, ‘OK, but that’s how the car works. “And she said,” But he has to show me that he can actually move his foot from the accelerator pedal to the brake. “And I said,” Ma’am, the car wasn’t set up like that. If he takes his foot off the accelerator and starts moving it towards the brake, the car will stop in the middle of the road. “”

Apparently, the agency was aware of regenerative braking issues with electric vehicles during test drives for several months.

In August 2021, Teslarati released a report detailing a similar failed test.

According to the report, “the DMV examiner informed the owner of Tesla that he had failed because of the ‘automatic engagement’ of the Model 3”. Explaining further, the examiner said she could feel the brakes even when the physical brake pedal was not depressed. “

The Teslarati report said the agency at the time “was working to ensure reviewers understand the function and its impact on driving.”

KPIX submitted a request to the agency’s public affairs office about the teenager’s complaint and received a response several hours later:

“Thank you for your request regarding Bryce Rosenblum’s Drive Test Drive. DMV’s Field Operations Division has reviewed the drive test score sheet and has determined that the drive test score will be reviewed as passed. The customer will be informed that their permit will arrive soon by mail.

The DMV has issued guidelines for personnel regarding the use of a plug-in hybrid electric vehicle (PHEV) or electric vehicle (EV) equipped with a regenerative braking system and / or a function. one-pedal brake for any test drive. If a customer uses a PHEV or EV with regenerative braking for their test drive, staff have been advised not to postpone the test as the vehicle is equipped with a regenerative braking system and / or a brake function. pedal braking, follow existing test drive criteria when scoring the test, and the application of the regenerative braking system should not be used as the sole reason for noting a driving error or a critical misconduct. “

The Rosenblum family praised the DMV for its swift response.

“I mean, I have to take my hat off to them for moving so fast, because that was just plain insane,” said Neal Rosenblum. “I think in the end I felt a little justified. So, yeah, that felt good.”
