It seems 16 is a best result I can get )
I think parachute deploy key can be safely replaced with repeated "Spacebar" press after the jump.
I saw road flickering at the start (perhaps it is some z-fighting issue).
Camera angle switch near the ground kinda throwed me off and made it harder to do a perfect landing. Maybe smooth transition instead of a sudden cut would be better.
Anyhow it's a nice take on the scene. Good work!
