I would play with the angles of the shot BEFORE your trip and see what angle you like the best. My suction cup mount has only fallen once but it was my fault, luckily tho the camera was inside the car getting a time lapse of a road trip. My personal favorite angles tho, are on the drivers door facing the road and you get to see the tire spinning then the road. You can trust that suction cup mount if mounted correctly, it won't go anywhere. GoPro has a solid staff and would always hook if something broke or failed on you.
