I have a GoPro 2 and used it on our first trip to AK in '12--it did real well in getting videos of everything at about 160d straight ahead. It suffers from 32gb card max and heating up that shuts it down. We just got a 4Silver that takes 64gb micro cards, and will use it beginning on June 4 going back to AK.
The 2 we had to manually turn on/off, as it was powered by a USB port on my truck that is always hot. The new one will work off a smartphone and be easier to control--I hope.
The battery life on these GPs is short enough to be a concern if you don't figure out how to power them from the vehicle. I don't know how the heat issue is going to be on the new one.
We had to hang it from the top of the windshield to a) minimize heat reflection from dark dashboard, and b) reduce amount of vehicle hood coverage that comes from the fisheye lens. It does have an auto upside-down top right-side up picture adjustment, so hanging it from the top the pics are still ok.
Have heard from a couple of Cobra owners who are satisfied with their operation/results, at much lower cost.
