Form and injuries
Form is an important factor for your driver.
A driver in bad form will not fully benefit from his skills on the racetrack.
On top of it, the age is taken in account in the form loss during races.
Injuries happen during races.
When your driver is injured, it is mentioned the number of days he's unavailable instead of the display of his form.
An injured driver is inactive. He cannot either race, practice or have a fitness session.
However, the age and the level of your health spa influence the driver healing.
Of course, a younger driver heals faster, and a health spa with higher level helps your driver to recover from his injuries.
The amount of days your driver in unavailable for is only indicative, and is calculated as if the driver was an 18 year old and your health spa level at 0.
So it may happen that the recovery time shows 7 days, but actually takes 5 or 15 days.
After 36 years old, a driver doesn't heal and the number of days increases ! The driver is then only good for retirement.
