Interactive Objects

Could we please get realistic physics on some of the quick drop items? 

I bought the tractor tyre.. it doesn't roll. 

I bought the boat... it doesn't float. 

We should have these items similar to the beach ball and soccer ball from skate 3. 

If you could float the boat downstream and as it's floating down you can hit a ramp to it would be epic and add another layer of skill and dynamics to the game. 

Cheers
