When Did Driving Stop Being a Skill?

Okay, I've driven all over this fine country, from New Jersey to San Francisco, from Canada to Florida. And drivers are pretty awful all over. So I just have to ask myself:

When did using turn indicators become optional? It's bad enough when someone in front of you suddenly applies their brakes for no reason, but the way people change lanes on highways and express ways is just maddening. Which leads to my next question:

When did safe braking distance start being an invitation for cutting? Remember the two second rule? You know, where you pick a stationary object ahead of you, count out loud "one-one-thousand, two one-thousand" at which point you should pass the object. Now, anytime I leave a little braking distance, again especially on multi-lane highways, idiots think I'm leaving them space to swerve in front of me. Oh yeah, multi-lane reminds me of another question:

Why can't people learn how to drive three (or more) lane highways? C'mon, we all learned this in Driver's Ed: the far left lane is the passing (speed) lane, the far right lane is for slow-moving traffic, entrance and egress. The middle lanes are travel lanes. I see more people driving for miles in the far right lane, making it nigh-impossible to enter the damn freeway. And, oh yeah -- the passing lane reminds me of still another question:

When did it become acceptable to pass on the right? I see this every day -- people pass on the right, sometimes cutting across two or more lanes on the right and then skipping back over to the left (usually without signaling -- see paragraph two.) And speaking of passing:

Why can't Americans learn how to drive a roundabout? There is a good-sized one a few miles from my home, in Tallmadge. Driving it is usually a nightmare. They have this down to a science in the England. Find a break, get on, move to the center (no passing) then SIGNAL and exit. Simple. One final question:

When did the yellow light stop meaning "prepare to stop?" Apparently, sometime when I wasn't looking, it changed to "Go like hell." And the number of people who think that using the light change to get through an intersection grew from one to three.

I'm probably not a perfect driver. But compared to most of the Cracker Jack licensed drivers out there, I'm a pro.
