I saw a fast ricer once, it was in my rear view mirror. Stayed right with me no matter how fast I went. Might have had something to do with the chain that it was hooked to my car with...
My Fiance's kid got sucked into that aftermaket ricer crap. He was browsing in the used Boeing aircraft parts section and picked up a wing. He mounted it to his trunk lid and then proceded to complain that he couldn't keep it going straight down the highway at speed. Now it sits in the basement all cold and alone.
