The problem is so bad in the USA that it causes huge economic losses … trafic jams where none should be, and highways with entire extra lanes that they should not need.

Current speed limits are not about safety - the current conventions were established in the days when cars had drum brakes, cross-ply tyres and truly abominable handling. A modern shopping trolley like a Honda Accord easily outperforms the best sports cars of that era, especially in cornering and braking, and has low profile radial tyres, decent suspension, and assistive safety technology like ABS and stability control.

The problem with any driving standards laws in the USA is that highway enforcement is primarily a revenue generating function, and you can’t measure incompetence with a radar gun. This law is not only badly framed, it’s pointless. Note that the USA is the only country where speed limits are set by local fiefdoms like counties, rather than by national road safety standards - do you really believe councilman Billy Joe Jim Bob understands road safety better than someone at NHTSA with a degree in engineering? No, it’s about revenue.

In Europe, it’s tacitly understood that the 1970’s-originated speed limits are artificially low for modern technology, and by comparison, the cops are far more relaxed about enforcing them … in most jurisdictions, 85 mph is the norm on motorways in the UK where the limit is 70 mph … but the old limits give the cops something to go on to write tickets to idiots who were doing something else stupid, that is objectively measurable and not subject to debate in court. This understanding of course relies on the cops exercising appropriate discretion, and is arguably untenable in the very adversarial context of the US police relationship with its citizens.

Maybe it was the cruise control or just too much traffic but lane discipline in America has all but vanished. I am older now and readily admit to driving like a geezer. My job requires me to drive on I-83 often (between Harrisburg/York PA and Baltimore MD) and I am amazed that in rush hour traffic I am slower in the right lane but relatively unencumbered as the left lane has turned into some sort of informal main lane of traffic now. It’s particularly embarrassing to see the right lane start moving faster because fewer cars are in it. I think people perceive they will held up by a large truck or slower traffic - it does happen but the fear of it is not congruent to the event. The highway would have no capacity problems if motorists would simply return to the right lane after passing. I have often joked to my wife that I need to get a photo someday of the phenomenon - Left lane completely congested while the right lane is clear.

Citizens serving as unlicensed enforcement officers won’t work. Ever try to report on neighbors driving irresponsibly and disobeying laws? My experience (and other neighbors’) shows that hatred, retaliation and property destruction are the rewards. In addition, bad drivers typically don’t want other drivers like them held responsible as it means further cuts to their preferred behavior.

As Davey Bob points out, the left lane owners like to hug the lanes to the last second before cutting off numerous other drivers to make their exit… these bad habits are multiplying and enabled via speed and ignoring safety.

I suppose that the only way to hold drivers accountable is to have electronic devices in every car which would automatically issue speeding tickets, red light running, rapid lane changing, etc, to their owners. Our public roads create more death, destruction, property damage, and serious injuries to more citizens than anything else we do and most drivers want all of this to be viewed as simply “accidents”.

One tidbit I recall about driving in Germany is the fact that a lot of German drivers really dislike the increase in foreign drivers and truckers on their roads because they don’t know the rules and are nowhere close to as well trained as german drivers. IIRC there have been several serious crashes on the autobahn in recent years that were attributed to foreign drivers screwing up, following to close, or losing control.

People in the left lane - who know they need to take a specific major exit - continue driving in the left lane as long as possible. Then, because they are ‘The Most Important Drivers on the Road’, change lanes at last possible moment, cutting in front of all the other drivers who have already moved over into the right lane, ready to exit the highway.

I especially see this with drivers exiting the HOV/carpool lanes.
