The chicane might have been erected two hours before, but if I recall correctly they started working on the design the night before. Adding a chicane to slow a dangerous section is hardly new, either. In other words, I'm confident that some bright guys would (and probably did) work all night to design it just in case.
Heck, add a morning practice session, and give the fans a bonus instead of screwing them. Allow them to add a specific fuel allowance to cover practice, or not.
