Here you are very wrong. Look at https://www.cdc.gov/motorvehiclesafety/seatbelts/facts.html#...
or https://en.wikipedia.org/wiki/Seat_belt
> In another study that examined injuries presenting to the ER pre- and post-seat belt law introduction, it was found that 40% more escaped injury and 35% more escaped mild and moderate injuries.[83]
I don't know how many bugs can use of all possible explicit typing and compiler warnings avert but I'd wager that it would be at least as high a percentage.
