Agreed, the OEM turn signals are self canceling. However, following a slow speed turn, the signal stays on too long before it self cancels which alerts others that your signaling to initiate a turn either right or left. I recently had a near miss incident where as I made a right turn then slowly proceed straight away. A car was exiting a parking lot driveway on my right onto the street. The car continued to advance onto the street as I approached closer at low speed. The right turn signal was still active at this point which falsely alerted the driver of the car that I was going to turn right into the driveway avoiding his vehicle. As a result, he pulled out blocking the entire lane as he waited to made a left turn into the other direction lane. Fortunately, I was able to avoid a T bone collision by controlled braking in time.
