On May 30, 2023 at approx. 11:30am I was leaving the car wash located at 2330 Olympic Hwy. N. Shelton Washington. The automatic bar pushed me through the car wash to the end where it left you. There was a slight grade downwards to the highway (Olympic Hwy. N.) I touched the gas peddle slightly and the car surged forward across the SB lane where a car traveling SB had to slam on its brakes to avoid a collision. My car continued across to the NB lane where it struck a vehicle in the drivers side rear quarter panel. I had slammed on the brakes but not quick enough to avoid the collision. The brake was slow to respond when I applied them. I'm thinking what may have happened as this is a gas electric hybrid that the gas engine kicked in instead of the battery when I gently applied the gas peddle which caused it to surge forward.
