He really doesn't give a damn!
In our vast experience of reporting exotic and supercar crashes, never have we seen a driver look so happy after wrecking their ride. Sources on the ground in Beirut, Lebanon, claim the accident occurred during an "exotic car ride" or "street race." Given the speed these guys are going, we suspect the latter was taking place. Thanks to Omar Dadoun we have a couple of images of the aftermath, the most striking of which features the driver of the GT3 who looks positively proud of flipping his ride onto its roof.
Either that, or he's simply happy to still be alive. Hat tip to Omar Badawi and Omar Dadoun for the pics and video.
