The debate on the day was about the difference in closing speeds an the differential pace of the so called A and B teams. For me that debate is about drivers having an awareness of all the conditions on the track and many racing series throughout the world have slower cars on the back of the grid and even multiple categories in the same race. This debate will run on but I want to explore track safety.

There may be many variances depending on the type of damage and the effect of the impact on the initial impact speed, but Webber's car lifted in a classic back flip scenario. when almost vertical the bottom of the car struck an overhanging advertising banner and was very close to the top of the the perimeter fence meaning that it may not have been contained if it had struck the fence. In most instances I can't see a problem, but there is a risk particularly at the street type circuits of Melbourne, Monaco, Montreal,Sinapore and Valencia where the tracks are narrower. The other perhaps bigger issue is bridges. Webber was immediately unsighted and said he feared hitting a bridge. Most tracks have them and whilst the closing speed to a bend can be dealt with, by providing more run off or higher fences, bridges ar often built over straights where speeds are much higher.
I am not a jobs worth Health and Safety person, However, there would seem to be a risk that needs some investigation. The FIA will no doubt be considering every detail of the accident in terms of rules and also car/track construction. It was a credit to the FIA and constructor's previous work over the years that Mark was able to walk away from a fuel heavy car which also retained all of it's wheels right up to the final impact.
The race itself was great and provided more drama in the shape of an overtaking manoeuvre by Hamilton who overtook the safety car as it left the pits. This resulted in an advantage not shared by alonso who finished 9th with Hamilton retaining second even after serving a drive through penalty on a slow pit lane. 9 drivers were awarded a 5 second penalty for going too slow in the 3rd sector retuning to the pits. This rule prevents cars from speeding in after clearing the safey car. The penalty variously affected drivers with Button, Barrichello, Kubica and Sutil retaining places and Alonso and Rosberg being promoted whilst Buemi and De La Rosa were demoted
