i bet if one track required a tray the safety record would blow all the other tracks away. a lot of ways to prevent sloshing...seal the back/front, require some maxi-pad-like lining in the bottom. remember, a leak generally does not dump 6 qts down all at once.

perhaps some tiny ventilation holes in the tray would keep the gas fumes flying rearward....the fumes are more dangerous than the pool. OK, the tiny holes might leak some fluid, but not enough to bring down the entire car. am i the only one who has seen several nice cars destroyed because of a fluid leak ahead of the firewall? it seems like it.
