If you want an interesting read, check out the battle over seatbelt interlock devices. Optional seatbelts (with perhaps fines for non-use depending on the jurisdiction) was the compromise between none at all and cars not functioning without them being in use.

That was a really interesting read, thank you

I guess we have Elizabeth Dole to thank in part for near ubiquitous air bags and seatbelts.

I hate to think how many would die every year without them.

These days? Few.

In the 1990s, more.

Except in the highest speed crashes frontal airbags are mostly redundant for belted in passengers (the first S in SRS is there for a reason), especially in this age of seatbelt pre-tensioners.

Side curtain airbags are far more helpful these days.

Are you pro-motorcycle helmet as well? I don't ride but my understanding is there is disagreement about the relative protection of a helmet vs compromised visibility, yet most states in the US mandate helmets. Maybe some motorcyclists could clarify.

Plenty of motorcyclists would also argue that louder exhausts are safer but the data doesn't bare that out either.

Yes I'm pro motorcycle helmet.
