I don't know when it happened but I found a bug. For some reason I had my health regen supportive part equipped(forgot the name) and before I knew it all of them I had equipped and in my inventory all changed to energy shields.
There should be tournaments for money. You pay to join and it lasts for a couple hours. there would be a ranking chart for 10 places after with a random card and high money reward for 1st 2nd and 3rd then just a moderate money reward for the rest of the ten.
It can be hard to keep control at very high speeds!
