Hi Dick,
Is the heat wave out there getting to you? We've had one of the coolest summers in a long time here, with plenty of moisture. Not very Colorado!
I test drive a lot of cars, some not in exactly pristine condition. When the signals don't work, I use the correct hand signals, as described (corrected version!) People think you're waving to them, or expressing something offensive in another hand language (That's the only explanation for some of the "replies" I've gotten) or that you're nuts. (well....)
Of course this contrasts even more vividly for we who actually bother to embrace the strange idea that one ought to signal one's intentions while operationg a motor vehicle. Many seem to think we should intuitively know what they intend to do. Besides, come on now...
How many hands do you think the poor dears have anyway? Steering wheel, cell phone, ooops, that's it. We got our priorities ya know.
I just saw the supreme embodiment of this phenomena on the 'net. A young flat bed tow truck driver was returning to base with a car on the bed. He hit another car, bounced off it, careened across a lawn and backyard, and then into a swimming pool. His reason? He was busy talking on one cell phone while texting on another. I guess he didn't have any hands left over for that pesky driving stuff. Poor guy...
