Really? All you have to do is lift your right foot very gently until you have the expected spacing again, no need to sudden changes of speed and if you have traffic aware cruise control it will be done for you. My old Tesla S does it pretty well. I keep it set to three second spacing and when someone cuts in front my car just gently slows down until the spacing is correct again; it doesn't brake unless the car that cuts in is very close.
If this doesn't happen to you, then you're probably driving like I do, and not leaving 3 seconds of follow distance like they teach in driver's ed.
Everything I've read points toward larger margins of safety (longer distances, slower speeds) being safer.
See e.g. https://publications.lib.chalmers.se/records/fulltext/252480...
We don't live in an ideal world, and having a bunch of cars merging in front of you definitely makes you less safe than having a static situation. I try to make sure I can see through/around the car in front of me, so that I have advance notice of what's happening down the road.
There is no solution to traffic here sorry, this is more about managing your own frustration and expectations when faced with people at their worst, in the worst form of transport.
The total, confirmed, 100% effective solution is to never commute by highway during peak hours, but few get that option.
But we all know that's not the case. Prospective purchasers are well aware of zoning laws. Same reason you can't build a fuel refinery on your tidy plot of R1 land. It would put existing owners, who have a reliance interest in existing zoning laws being respected, in an awfully unfair position.
Incredibly frustrating, and I've driven all over North America - there's practically no major city where this doesn't happen. If you're not maintaining a safe following distance on city/residential streets, that's a different matter.
And in this case "local laws passed by voters themselves" are one of the causes of the state's housing crisis. I think the state has a legitimate interest in overriding local laws here.
Like if you don't want high density in your neighborhood, buy all the houses. Form a neighborhood association and buy every house that's put up for sale. When selling properties, include covenants restricting resale to a developer, or giving the association first right of refusal. Spend your own money. Don't use state violence to achieve private ends.
While I would place state laws passed by popular vote above local laws passed by popular vote, I would say that laws passed by representatives, without much awareness of voters that this was their intention, should not necessarily be put above local laws passed by voters themselves.
