Race only feature - power ups hidden behind?

Random power up, its a question mark for every one, every time. What will it be when you activate it??? Truely random, pick it on a hill just before an attack or coming into home sprint? Well you wont know what it is, it still will be an advantage, just not as much as you were banking on and would make the commentry so much fun.

I like this suggestion. I hate when I don’t get a power up and just a few points. If I could get a random power-up instead that is unknown until it is used, it would make it more exiting.
