This is a great example of the importance of teaching people critical thinking skills.
If you stop to analyze what was written in this sensationalized post rather than acting on your emotions, the first question that should come into mind is "who stopped them?". There are no checkpoints between Oregon and California where cars are turned away from crossing state lines due to emissions. In fact, that would probably violate federal free travel laws which would supercede any stupid law like that.
Next, consider the source. Is this person trustworthy? Did they provide ample citations to reputable journalistic outlets that verified the factuality of the claims? If not, they may be trying to deceive you with falsehoods or have an ulterior motive for misrepresenting the facts. At best they are repeating claims that they've heard from others and anything they report on should be taken with a grain of salt.
This post doesn't hold up to the slightest amount of scrutiny, but people get fooled every day by crap like this. My advice is that if you hear something that sounds outrageous or too good to be true, stop and think carefully about it for a few minutes, or maybe just wait for another source to report it. Saves you a lot of stress and protects you from endlessly doomscrolling.
I see goof-ups like this all the time in the NMLS system. Someone thought they were inputting the price in the thousands and meant to list it at 4.7 million, or this is actually a rental and the monthly cost is $4,700 which still seems quite low for such a large property.
Back when I was house shopping I would gets automatic forwards from my agent about "new listings under your budget!" and they would be crazy low prices like $600 or something. Takes a few days for the listing agent to notice their own screw up and fix the listing.
