I find YOUR demand for statistical support to be alarming. Or humorous. I can't decide.
For a guy that throws out (up) things like, 90% of drivers should not be driving, without any support of the statistic you make up, you demand far too much support for a casual observation made by others.
You have used your 90% figure numerous times in a wide ranging set of discussions, and your only support at the end of the day is, "I drink on the porch swing, watching the world go by." You see something, blink your eyes because a fly landed on you, and when your eyes open again you see something and count the event as having happened twice. Another car drives by, you blink, two times you see something happen. You can get to 90% pretty easily like that...
