For this test, I had the camera on a mini tripod, balanced firmly on the dash of the car.
Unfortunately, the windscreen is a bit dirty. But I'm only testing the stabilisation feature in this case.
EIS (image stabilisation) was ON
Firmware version 1.06
Notice the wobbly effect when the car is stationary in the beginning? - image stabilisation issue, hopefully fixed in next firmware update.
I'll upload another test, with the setting off, soon
