Challenge rewards

I really am enjoying Skate. I have been eager to play it, and waited a long time for its release since Skate 3. I like almost everything about it except for 2 things mainly. 

1. the purple trucks tokens you get from completing challenges become useless once you unlock the 3 parts of the map. I currently have over 12,000 of these tokens with nowhere to spend them. I think there should be some items in the shop you can purchase with these as well so that people still have an incentive to finish challenges. 
2. the climbing can be annoying. I want to skate not play assassins creed. A fast travel option to the top of all the tall building would be nice, as well as the spiral ramp in market mile.
