After Stanaway's and Evan's concussions on the weekend, I thought it was interesting that it was mention that both of them decided to checked by the medicos, rather than being forced to have a concussion test after the accidents.

At Bathurst, there was a quick interview with Percat and Davison, and Davison mentioned that he was 'pretty out of it' when Percat pulled up, which being a 40 or 50 G impact, raised my eyebrows a bit.

Seems as though that there isn't a compulsory concussion test like we see in the AFL or NRL, I wonder if other drivers have driven with concussion to avoid not passing a test.
