about the open/closed ****pit: The manufacturer's decision to run any class, such as the open prototypes, specifically the LMP900 class, is dictated by the fact that the rules as stated by ACO make that configuration the most likely to win. You'll notice that the Bentley was the only closed prototype this year, I'm pretty sure. Just an interesting side note, it was running the Audi engine...Anyway, Tire size, engine size, weight, gas tank size, engine power, etc. are all very specific for each class, and there are advantages and disadvantages for each. As for the safety, they are just as safe as the "tin tops"; every car has to meet crash standards. The only change in regards to open seat safety is that, if I read the rules correctly, the LMP900's will have to return to a full-width roll hoop instead of the current CART-style that is just over the driver's head. For an example of what I mean, look at an old Riley and Scott Mk III chassis, or a Ferrari 333sp, versus the BMW V12LMR (which started the trend) and the Audi R8R, R8. CART cars are very safe, Zanardi, Rodriguez, Moore, et al. not withstanding. A closed ****pit on those cars would most likely only be beneficial from an aerodynamic standpoint, as it would on any open ****pit car. Besides, the closed top prototypes were sometimes more interesting to look at...
