It's extra weird given that earlier in the race, whilst behind Sam Bird, Simms clearly let Da Costa through in an orchestrated move so they were flying in team formation.
Maybe the deal was that Felix Da Costa would let him back through if they both got past Bird? I dunno. Very odd though.
Having said that they won't be the most worried if the German manufacturers. The top brass at Merc turned out to see the HWA cars collide at the start and trundle round at the back. Whilst Audi saw their customer team completely out pace them all weekend.
