This morning on my daily walk I happened to think about the old hand signals for turns. In driver training we were all taught these: left arm straight out the window, left turn; arm cocked at a 90-degree angle, right turn; arm downward, slowing down. Now, it occurs to me to wonder if anyone under about 50 would even recognize these signals today.
What? You say we don't need them because turn signals are electric? Twenty years ago I might have agreed with that, but in my observation nowadays, we're seeing a trend away from using our electric turn signals. Judging from how many folks I see NOT using them at all, it seems there are a lot of people who are worried it will run down their batteries, or cost them too much in replacement bulbs. So maybe we should revive the old hand signals? Pie in the sky, of course. People who can't take the trouble to signal a turn with a simple flip of the wrist from inside their air-conditioned, roofed cabin certainly aren't going to take the trouble to get a window down and stick their arm out of it, taking a chance on it getting wet or hot. I guess it's more likely that manufacturers will just stop putting turn signals on vehicles (which may occur about the same time they stop putting hand brakes in them).
I'll miss them, if only for the little turn-signal memories they evoke:
A foreign visitor once quipped to me that it seemed turn signals were optional equipment on cars in the U.S.
Ah, but that visitor was from northern Europe (U.K. or Germany as I recall). In Rome, and in many crowded cities around the world, turn signals aren't generally used at all, and progress in driving depends on taking advantage of every little opening to edge forward, while never, never looking behind you.
Turkey was somewhat like that too, but one difference we observed was that Turks often seemed to clock about as many miles in reverse as they did in forward gears. By that time (late 1980s) cars of course had backup lights, but as often as not, these seemed to have burned out (maybe from overuse?) or maybe had just been disconnected on the theory they gave an unfair advantage to the following driver.
In Liberia in the mid-1970s there were only hand signals, and there was only one: An arm out the window, hand flapping idly, meant: (a) I'm turning right; (b) I'm turning left; (c) I'm doing a U-turn; (d) I'm slowing down; (e) watch out, police ahead; (f) the bridge ahead is washed out; (g) I'm thinking about doing something, but haven't decided yet; (h) I spilled my drink on my hand; or (i) nearly anything else. But the system seemed to work.
In Paris in the late 1940s I remember the old Citroëns with the turn signals that were mounted on an arm that folded flush into the car body, but would snap out from the space in between the front and rear doors when you activated them.
A recent weird variant of turn-signal placement has popped up on the market just within recent months: At least one maker is mounting turn signals and brake lights very low on the rear corners of the vehicle; they may even be embedded in the bumper. Although I don't have the details of make and model, two things are clear to me: These signals are too low to be readily visible, and because of their placement, they are going to need to be replaced after the least minor fender-bender. A bad idea, I think.
