On July 21, I was stopped behind another vehicle. Using 1 pedal driving with no roll feature. There was front camera error message as well as traction control warning light on. My car started to move forward on it's own so I inadvertently hit the acceleration initially before I stepped on the brakes - car did not stop initially and I rear ended the stopped car in front of me. Lucid kept my car for a week reviewing the logs and concluded there was nothing wrong with the vehicle and the incident was driver caused. I have never stomped on the go pedal from a standing stop before. The car moved forward on it's own before I inadvertently stepped on the accelerator pedal.
