No I turned it off as we got into the boring traffic bit. It was the only run where there was not traffic on the road. I was lucky to be there prior to the real start of season and so the roads were still moving.A week later the tourism busses started and it almost comes to a halt.
The pack came with 2 batteries (unlike the expensive GoPro) although it is a bit of a devil to remove the small plastic lid and change them (de-mount it).
