> When you've lost someone in a car-accident it's not much condolence to know that e.g. an airbag could have saved him/her but "back in 2026 it was deregulated because the car-companies have proven that there's no economic benefit to include them"

We live in a society, etc, etc. I think it's worthwhile, or even _more_ important, to look at how these impact other people.

In some hypothetical deregulated world, I can choose to buy a car without seatbelts, air bags, ABS/TCS, reverse camera, etc and take that risk on.

My neighbour doesn't get to choose whether or not they want to take on the risk of me backing over their child. The other people on the road don't get to choose whether they take on the risk of me losing control of my vehicle and slamming into them.

The value question isn't purely economic. Regulations that force a general societal care and consideration over selfish individual choices have value in _allowing us to have a society_.
