Well, honestly they’re not really good for anything. Most manufacturers use a bake type method, which is not in anyway comparable to a house engulfed in actual flames.
As a general consumer, this is about the best you can do. Put whatever in a “fireproof” bag inside a “fireproof” safe and you might save your data in the event of a fire.
It’s the same thing about gun “safes”. They’re not really safes unless you spend big money. Like $10,000+. Otherwise they’re categorized as “residential containers”.
I should have clarified whether or not my answer was in response to “is it possible” instead of “is it recommended”.
Doesn’t seem like that would be effective on something like the interstate highways. I’d imagine actually fining people would work.
An area close to where I live turned on speeding cameras for a work zone that’s been notorious for speeders. They clocked 38,000+ tickets in the first week.
One of them was for 106 in a 60 mph zone. I haven’t kept up with it since they turned it on but it was desperately needed.
Disclosure: I’m not any expert on road safety or driver psychology. Just someone that used to drive 50k+ miles a year and saw a lot of what I thought were trends.
