Perez is apparently alive and well, the 'crumple zone' having done its job and the barriers deforming nicely.
It's truly amazing the sorts of crashes an F1 car can sustain and leave the driver virtually unhurt. If I bingled my car at 290kph you'd be scraping bits of fat guy of the road for weeks!
Unfortunately, despite the atmosphere, Monaco is a bit of a parade. Barring misfortune or a truly lucky pass, the order rarely changes from start to finish.
Look forward to it, none-the-less.
