Yes. It has happened to me several times sitting at the red light only. I did not move around or have any unusual movement when it shifted to park mode.
I am still waiting for the update. Any suggestions or just wait for the notification? Just to be clear, I did not receive the initial buggy update to resolve the issue.
Just sharing...today I was waiting at the traffic light and noticed my R1S switched from Driving to Parking mode. I could switch back to Driving mode and continue to drive but it was a strange occurrence.
My windshield trim (driver side window) started peeling and flapping during my drive yesterday. :(. I pushed it back in and carried a tape until it is repaired.
