There are just a lot of Scooby owners who are techy types (it seems)
At the SIDC track days at Knockhill there is a high percentage of Unix/Network/Sysadmins driving P1's, turbos, WRX's etc.
Last I looked, out of a typical 20 cars there, 2 of us had Empegs (and amplifiers which glow blue in the dark to match), but everyone there had some gadgets.

Perhaps folk who drive 'driving' cars are gadget boys (tm).
