October 8 2020, 5:00pm. Heavy traffic on I-5 north at anaheim, ca near harbor blvd/ball rd exit. I had just changed lanes to the right in preparation to take the exit. Due to heavy traffic, my speed was approximately 10 MPH. Immediately after settling to the new lane, toyota rav4 in front of me brakes aggressively. I was about 6 ft from this car, and immediately pressed my tesla y brake pedal hard in an attempt to avoid collision. But, my tesla y would not stop. The wheels did not lock into full braking.
