Front-drive cars. That happened to me once, but I was cut off by someone at speed while I was in the center lane and I swerved. The car just spun off the road. Fortunately I didn't hit anyone and nothing happened to me.
WTF was his excuse? "I swerved, I braked, I swerved...". Shoot that guy. I kept looking at the footage to see if there was an exit he might have missed, or something like that. Nothing. Out of the blue that guy just phucked up.
I hope she's OK. I'll assume she's the one that posted that video. I wonder if she was wearing a back protector, as her back was hurting. She looked pretty well geared up otherwise.
