I’m personally for seatbelts* and against mandates for their use. Giving the government another tool to meddle in the lives of people and a law that’s easy to selectively enforce seems like a worse tradeoff than a few people who will decide to not wear one and avoidably come to grief as a result of their choice.

* To the point that I added them to a car of mine that didn’t originally come equipped with them. I like them and wear them regularly by choice, as should be the case.
