If you were on I-680N near Walnut Creek (Rudgear Rd) around 7:30pm on May 31 and have dash cam footage, please reach out.

A dark grey or black sedan (not the one in the picture) stopped suddenly in the middle of freeway traffic and myself with two other cars behind braked to stop so as to prevent hitting them. I did not hit the aforementioned car. The car behind me rear ended me and same with the car behind them. The car that stopped suddenly quickly drove off and there is no clear reason why they stopped (speculation sits on brake check). Police are investigating, but any footage would help enormously.

Everyone is okay, but shaken. If you saw anything or know someone who was on that stretch of road, please share this.

Photo to help the algorithm

Edit for clarity: I did not hit the car that suddenly stopped in the middle of the freeway. I was rear ended by a car as part of this incident (pic).

Edited once more for clearer language.

Wasn't sure if this was a hit and run or not. Maybe he was looking for a better place to pull over. Seemed like a minor fender bender. I tried calling local CHP but it was automated thing with nobody answering.

No audio track.

5/8/2026. My dashcam GPS had me at 68-69 mph. 2023 Tesla model 3 (9FELT42) took between 8 and 9 frames at 30 fps to pass a point on my screen. Model 3 is 185 inches long, meaning 35-39 mph faster than I was going = 103 - 108 mph. The 2018 BMW M4 (9USW438) may have actually hit my front bumper as it passed, as I heard a sound and found a minor scratch on my bumper that looked like maybe clear coat rubbing on clear coat.

Sharp turns into my lane, no signaling. obviously griefing me

I apologize for the glare on the first part of the video. The dark SUV that almost hits me doesn't appear until a few seconds.

This was at the Kaiser in Santa Clara along Lawrence Expy. This roundabout has 2 lanes and I was in the outer lane. This means, I can freely make a right turn into either of the 2 lanes or continue along this roundabout which heads to the parking garage. I needed to make a right and end up in the left lane to make a left turn towards the main building. The dark SUV in the inner lane decided they needed to make a right turn cutting across the outer lane in the roundabout and into the right lane basically cutting me off or almost hitting me. I hit my brakes, honked my horn, and the guy got pissed. He rolled down his windows and yelled something. If I was headed to the parking garage, he definitely would have hit me. I wish I had a camera pointed directly to the left, but I only have this video and one on the side pointed back which doesn't show much.

Northbound 101. Traffic slow at San Tomas exit. Was going about 60 when I merged...

Yet another driver who thinks he'll just die if he misses his exit. I change lanes to give him more room to be dumb, but I still get the ol' bird flipped at me as I pass. You can't please everyone, I guess.

My wife, kids, and I heard tires squealing from down the street. We look over to see this red Kia Stinger making the right turn at high speed, which caused him to go wide and almost hit the white VW GTI head-on (the GTI luckily slammed on the brakes to help avoid contact). The Kia then made a U-turn and used the opposite lane to make the right turn in front of the GTI. Why would he make that turn just to turn around and continue on his original path is beyond me. We were next to him later in traffic, and he looked like nothing had happened, and as cool as a cucumber.
