Did an Indianapolis Speedway endurance with a fully upgraded with the McLaren P1 GTR.

Raced 21.25 km without off-tracks or colliding and did 17 bars of 'damage'. That's 1.25 km per green bar so no change in servicing requirements.

Raced another 21.25 km without off-tracks but this time colliding with every car overtaken. Still only 17 bars of 'damage' done to the car. Also 1.25 km per green bar so no change in servicing requirements here, either.

When I wrote my blog two years ago, I found that you could drive 1.25 km / bar. This still appears to be the case, to this day.
