I've noticed the same shift.
Drivers are worse now than 10-15 years ago. Drivers are more aggressive (tailgating, rolling stops, speeding, ...), more sociopathic (tinted windows, louder pipes, larger vehicles, fake license plates,...), more negligent (bald tires, texting-and-driving, bumpers ripped off jagged metal sticking out, ...).
Another data point. Dashcams are on the rise, and they are truly the indicator technology of a low-trust society (remember the early car carnage internet videos, those were nearly always from russia or eastern europe, good times!). Wherever dashcams flourish, social contract is fraying.
It does not have to be like this. Many countries in Europe are making quite the opposite shift. Just recently was in London. Unreal! That place is so much more airy and welcoming than just 10-15 years ago. Covent Garden was positively quiet; so many electric cars and utility vehicles, much slower travel speeds, fewer streets, ... phenomenal. Once you experience it, and especially if you have a memory of the dark times, nobody in their right mind will want to turn back.
And wrt:
> People suck.
Do allow me a short digression and light hyperbole.
Maybe it's time to start pointing fingers, something americans, especially on the progressive-side, are too squeamish to do. In City of God, St Augustine blames the fall of Rome on the christians in the city ignoring the depravity of the pagans. Maybe we should take heed his advice, and it's time for the righteous to start calling out the wicked. Some people truly are crap, exhibit trash behaviors, and are making the world, quite simply, _worse_. We need to be confident in our judgements, and have the courage to clearly delineate right from wrong. As americans, live-and-let-live is ingrained in our DNA, but d*mn somethings gotta give here, drivers are really out of control.
