Thos ricer fly by's are as sure as they come! The fly bys that aren't really fly bys though are when they are actually catching up (never happens, not saying it happens or will ever happen to you) like when my brother races a ricer and loses like 0 - 30ish (very bad traction) in his Impala SS but begins to make big gains then the rice throws on the flashers and slams the breaks.
Boo!! Especially when they know they would be passed!
