I think the thread starter should clarify certain points in the original question. Because topic is escalating to surface tension or maybe even interference of angels. What does it "get" means? Does it mean "absorb" or "collect" the water (like a spunch), or number of hits that car will receive? Up until this point, more, less, and same rain theories are all considered by different suggestions. However we still could not find an answer for thid speculation.
