EPA regulations are designed to encourage better gas mileage, but they are based on vehicle size. So instead of making more fuel efficient engines, auto makers realized they could just make bigger trucks with the same shitty engines to meet the guidelines.
At least with that example, the products are related. Amazon lets sellers replace listings with completely different items - new name, picture, and description. So you’ll find a scam 64GB USB drive that’s pretending to be 1TB with hundreds of positive reviews, but when you read those reviews, you realize they’re for the plastic fidget toy that shared the item number previously.
I knew someone with a newer model (2019 I think?) Honda Fit with the emergency braking feature. It did absolutely nothing to prevent them from running into the back end of a pickup truck that swung out in front of them and slammed on the brakes. Literally it didn’t engage at all.
Also, the interior room on the Fit is terrible post-2013 due to some design changes. My 2010 Fit was a TARDIS - a 6’, 400lb guy could ride (or drive) it comfortably. That same guy riding in the 2019 model was cramped as a passenger. We didn’t try asking him to drive, after seeing how he fit as a passenger.
