So.. are the grinders destroying the planet? If one grinds 2.2M 8h autodrive races for the expensive cars, thats 140W per hour if just the ps4 is running. This gives you equivalent of approx. 10180W per 20mil car. So you use 10kwh of electricity per an unicorn. Thats 1-1.5$/€ in your electricity bill. Not quite the effect of crypto currency mining, but thousands of people doing this on top of the usual playing hours is far from optimal. I plead to PDI to close this possibility for the planets sake and give us a way to collect more credit by playing. Give us that 2,2m for say 1 hour of demanding racing instead.
