1. i was using tesla self driving standard on my vehicle it accelerated up to 19 miles over the recorded speed limit. 2. The speed limit was 55 and it went to 74 way to high and no way to lower it manually 3. Confirmation by the MD State Police radar 4. No inspection 5. There was no warnings. Consumers should be able to set the maximum speed desired or lower it if it goes to high manually, but you can't if you are using self driving options. You can go to chill which is the next level down but that is to slow. Consumers should be able to manual put the speed where they want to drive and feel safe. I was between two cars in the right lane driving down the highway. I believe my vehicle was keeping up with the flow of traffic but no way to slow it down unless i went out of standard self drive. Chill is the one below standard and that is to slow.

The vehicle activated in Autopilot mode without my intentional input, causing me to lose control and resulting in a serious crash. Prior to the collision, the vehicle's Autopilot system, engaged without my input and abruptly accelerated. I was seriously injured as a result. The vehicle, a brand-new 2024 Tesla Model Y, was in normal operating condition with no prior mechanical issues. I had not modified the vehicle in any way. Following the crash, Tesla provided data to attorneys regarding the incident which I believe to be inaccurate and inconsistent with my experience. I am requesting that the federal safety agency: 1. Open a formal investigation into this incident 2. Investigate the accuracy and completeness of data Tesla provides following Autopilot-related crashes 3.

The Tesla Autosteer (equivalent of adaptive cruise control) failed to brake on seeing the car ahead braking. In the 5 seconds before impact, the car ahead had started braking. The autosteer did not brake for the first 3 seconds and then It asked me to take over 2 seconds before collision. It did not apply automatic emergency braking causing me to rear end the car ahead of me on the freeway at around 30mph This is supposed to be a safety driver assist feature which instead was the primary cause of the accident. The take control was too late to avoid collision. This is a serious safety issue.
