The Most Expensive Part on a Southern Californian Car

Riding a very busy southern Californian highway each day for roughly one and a half hours gives one ample opportunity to observe plenty of aberrant and abhorrent driving behaviours. Being on a motorcycle one feels a little more vulnerable than usual and so simple-minded absences on the part of other drivers can become a dangerous situation. Of course, that's part of the charm of riding. :) However, two behaviours that I have seen repeated so often have lead me to theorise on that part of a southern Californian car which surely must be so expensive as to put it's cost out of the financial reach of the average driver. Lest they damage it -- and their savings account -- beyond repair very few seem to place their hands near the turn signal (indicators in Australian parlance) control. Turn signals rarely come on -- I'm now convinced it is a privacy issue for these people -- and when they do, they rarely go off.
