RAGE. Your DH has his head up his *ss, and he should know better by now than to pull BS like this. Whether or not he believes you, it is never his right to take risks on your behalf, without your consent. That's a HUGE breach of trust.
I'm going to respond at more length privately, but here are some terms that have helped me contextualize it with M and others; might help your DH wrap his head about what needs to happen on a purely practical level (if not the whole belief issue):
Sometimes, it's not just about being safe. It's about feeling safe.
It's not just about cut-and-dried physical safety. It's about being able to relax enough to be a person rather than having to stay in hyper-vigilant high alert. What that takes is not always objective, or fact-based, or proportionate, or strictly physically necessary; but unless accommodating it causes prohibitive hardship, there is no good reason not to.
And it is never, ever, ever, ever okay to take or force risks like that on someone else's behalf without their informed consent. Never. NEVER.
