Easy points hint:
Skate to the vending machine in the small gas station by the skate
park. Push the Nunchuck stick toward it and wait a couple seconds, and
then your points bar will increase by 50 each time.
More Adrenaline and points hint:
For more adrenaline, hit vending machines, electric boxes, security
cameras, ride on drones. You can also find Adrenaline Packs on ramps
etc. (Grind or Jump)
