In some ways that is the answer. Crashes keep happening because they are not being held accountable to regulators because they are not reporting these incidents and no one is exercising oversight to be sure the reporting matches reality.
I think over the years, accurate reporting by manufacturers has been done because they generally do not want to be known as that car company that killed a child and it could have been prevented with a 50 cent bolt. As a result, regulators have been less hawkish. Of course there are probably political donations in the US to help keep the wheels turning.
In many ways democracy is a lie. You still have a system of government that puts a handful of people in fairly powerful positions. These people will always do what is needed to keep the power they have.
For centuries democracy has focused on the elites. They have done a good job of keeping participation low and therefore creating an under informed population. Commonly in the US, you’ll hear phrases like “It doesn’t matter who I vote for.” “My vote doesn’t count.” “They’re all the same.”
When you have a voting populace who has regularly not participated and talk with authority to them, you can get them to buy whatever you’re selling.
