Hand Waving Patterns of Porsche Drivers
 

I thought this was funny:

Magazine: Total 911, Issue 6 Nov 2005 pg. 40 by Ben Przekop, Roswell, USA

He stated as a previous MGB owner he felt Porsche drivers were less likely to wave back unlike MGB owners when passing by.

His own wave back testing found the following:

911 drivers = 90% wave back (the 911 Turbo Driver didn't wave back

Boxster drivers = 10% wave back

Cayenne Drivers = 0% because most were Soccer Moms on cell phones.
