My suggestions: Taking them at a different time of day might help. When the sun is that intense, the contrast from shadows can be a bit overpowering.
Try desaturating just a bit in some of the really colorful ones, and play with the temperature in 4&5.
If #2 was taken in that same spot at night, it would rock.
Driving on a more open road (not surrounded by trees) will make the motion pics better - as it is right now, there is almost too much to look at and be distracted by - especially the reflection of trees in the windshield.
Really good angles on all of these! You've definitely got an eye for it.
