There sure as heck wasn't an object on the road, visible. I'd have noticed it even if I still ended up hitting it, it's not like those little stakes are that invisible. IF it's a tire temp issue it never showed up in my longer runs on the same fuel load - that was on ~lap 4 in a stint and I've a done few 20 lap stints in that same car. I can only guess something oddly specific caused the physics to puke or there is something not rendering on the track / debris isnt clearing properly. And who wants to drive the Brabham? It only does 180, need moar speed!!!!
