With a basic rolling code that works and maybe still used in garage doors, but afaik current decent car alarms exchange encrypted keys several times between car and keyfob that you can't just replay.
Even simply generating totp based keys and invalidating them in a few minutes is enough to make that kinda useless in practice.
In the US, defamation requires either knowledge of falsehood or reckless disregard for the truth. It's not reckless disregard for the truth to say someone who's been arrested for a crime did that crime, even if it may be premature.
FPS are immersive, fun for an hour or so, but I'd rather play with keyboard/mouse/monitor anyway - I'm often tired after work and just want to chill for a bit. Actively moving in VR gear is more of an excersize.
Otherwise you can go play paintball/softball etc and it would be 100% better than any current VR tech.
I can play VR shooters at home. I don't even know how I would play paintball as they are far out in rural areas without public transport access. That's an anecdote but its not unique. VR brings accessibility to a lot of people.
