Were you there to just torture Vette's all day? Lol. Glad nothing happened! I think I would have tried to pull off to the left. But I can't tell what was behind you which is the real worry. I think this demonstrates the importance of being aware of who is around (and behind) you. Makes these quick decisions easier.
But, I would never assume anything with advanced drivers. I saw one guy go off and then come back on right after a crest in a hill. A Mustang came hauling ass (~80mph) over it just as he came back on.0 Luckily the mustang turned and locked up the wheels...it would have been bad. The Mustang also missed a yellow flag though.
