... but we all sped thru the rough section
as if we flew on wings!

The exposure was at 1/10sec (see photo exif data below).
You can estimate our speed, how fast we went here: These marks were photographed in 1/10sec,
so therefore, in one sec (ten times longer duration), they would have travelled from here to here (ten times longer distance)!
