Zekirja, If a driver's health is below 30% they will go slowly.....very slowly. Your drivers need to be fit & healthy to go quickly.
Their health will improve as you train physical or you could use some reward points to make them 100% instantly. Either way, their health is their most important attribute
If you use reward points to bring it up to 100% will it stay that way say you have a driver that is always 73% after a race and you have a good doctor will it go back to 100% after using the points or is it a one time boost.
The points will get you to 100%. It can go down to 73% during the race, but after the race the driver should be at 99% to 97%. It will always be a little lower than before the race which will force you to decide how to handle it. Go with the doctor training... or do physical training with each driver.
Best way to keep a driver fit is to train physical to the max before training anything else. A driver with full trained physical will never go down more than 99% thus giving you opportunity to train him in other fields and train your doctor after every race to get your driver up to 100% again. By the time you get your driver up in physical you would have trained all other staff to their max already so u will need to train the doctor only!!
I know im giving away tips but i was given those tips before. But you guys should really start try to understand the game yourself.
