I use the cruise control alot on my daily commute up and down 280 in the Bay Area. If i change lanes (manual steering) to pass a slowpoke, the car markedly decelerates in the midst of the lane change and then it speeds up. it does the deceleration if i step on the gas pedal to change lanes and pass a car and it also does it if i just steer into another lane and let the cruise control get up to maximum speed. Its incredibly annoying as the car lurches slow then fast. I think it is also unsafe as the last thing i expect when i step on the gas and change lanes is for the car to momentarily slow down. Anyone else experience this?
