I'd like to believe that olympiad is a display of skill, where the best player at its class gets the "hero" status... But it's not in most cases.
It might be a display of equipment that you grinded for, but in the end it is mostly earned by many other CP members or drivers. You might still go for the grind, but you will be heavily outweighted by the people who invest heavy amounts of cash.
Many randoms might see olympiad as a individual competition, but in reality it is heavily based on the faction that you are in. I would definitely prefer it to be the opposite, but it is what it is...
