Since seatbelts are in use the number of fatalaties in traffic have significantly gone down. In countries where people don't use seatbelts the fatality rate is still high.
I think it is safe to say that seatbelts help a lot more than they hurt, though there may be the occasional freak accident where not wearing a seatbelt would have been better.
How many people were killed by the faulty Takata airbags? 8? How many were saved by airbags? But airbags can only work with seatbelts.
Wearing a seatbelt is especially important for rear passengers. They don't just risk their lives like the front passengers, in the event of a crash they are also likely to kill the front passengers. Even if you only drive 20 mph.
All the safety tech, as well as most traffic rules help a lot to make the roads safer. With one exception. Speed limits. They don't help. In Germany people drive way faster than in the US, yet it is safer in Germany. People just pay more attention ay higher speeds, they drive better and in a more orderly fashion than in the US, and the reason is IMHO that the high speeds require that. Driving education is much better too.

If we're really trying to reduce personal injuries and deaths, the most common cause of injury and death, according to decades of emergency room visits, is falling down stairs in the home.
"Most common home accidents happened when walking up or down the stairs. Broken hands and legs are the usualy resulting injuries to an estimate of 2,324,938 people."
By contrast
"In the United States during 2011, more than 650 children ages 12 years and younger died as occupants in motor vehicle crashes, and more than 148,000 were injured."
Now I know I showed stair-use injuries for all people versus auto-use injuries only for children, but you see my point. Stairs are maore dangerous than cars!!!
Consequently we should mandate all new dwelling units be single-storey, and before title to a pre-existing dwelling unit changes hands said older dwelling unit must be retrofitted with some form of stair-use safety device.
And license all stair users. We license drivers, so why not license really dangerous activities like using stairs?
After all, it's for the children.
And it will hold down the cost of health care.
Stairs are just a bit more dangerous, and making them safer is nearly impossible. For cars it is really easy to make them significantly safer, and the benefits are huge.
In other areas what you say would make a lot of sense, war on terror for example. Only very few people die from terrorist attacks (especially in western countries), yet the cost to try to protect people from them is extremely high... both in terms of money and civil rights/liberties/things your founding fathers fought for.
