Snapped needles are the most likely thing that could happen.
Sometimes people assist the motor by turning the hand wheel, and I've heard that can bend the frame of the sewing machine in some cases. That'd be the most catastrophic failure potential I think
You can try a heavy duty needle, but there's a pretty good chance a domestic sewing machine just won't work with seatbelt webbing. I'd recommend caution
I hold this opinion with sewing machines as well. After working a Janome Mod-30 to death, I found a Singer 403A and I'm pretty sure this thing will out survive me (while meeting all of my needs). Removing the entire motor involved unscrewing 2 screws. Cleaning the commutator and checking the motor brushes involved unscrewing another 2 screws. I can't go back.
Those hicks are the ones that won't pay attention to if there's a crosswalk.
They are the problem.
Fuck catering to them
It's only cannibalism if you believe you are the same as God.
Arise, God-drinkers.
Alternatively, we will go extinct having never left this solar body because of the long standing history of scummy people that would rather make profit now than address climate change
It's a start, but 2fa can't stop spam.
If one can automate account creation including saving totp secrets, you suddenly have 2fa authenticated bots able to send spam.
Maybe you could get around that to some extent by leveraging sms verification during account creation, but how do you set that up to prevent burner numbers? Or smishing?
These are hard problems to address
I'm truly glad that it's helping someone; however, for every one of you there are a hundred people denied important procedures because insurance has decided its opinion is more important than the doctor's.
An easily available example off the top of my head is Styropyro's most recent video where he might have cancer but Insurance has denied his brain scan.
