Doesn't stop people from driving without licenses/with revoked licenses. There's also a *major* issue with people driving uninsured (why in the *fuck* isn't auto insurance just provided by the state, if it's a requirement to have it? Or at least for the "mandatory state minimums"?), and those things also tend to combine in the somewhat high rate of hit-and-run incidents. Which is then compounded by cops often not giving a shit about a hit-and-run unless it happens to a cop, the wealthy that use the cops to oppress the poor, or someone is killed by the hit-and-run.
Of all the things you can point to in the US, as an example of "how we could be doing guns better," pointing to our driver's licenses and traffic laws and stuff and acting like that's an example of an actually functional system that makes people safer is so fucking ignorant it sounds like parody.
Literally the only reason we don't have tons and tons of deaths from cars is because federal regulations have forced auto manufacturers to repeatedly install and update safety standards in vehicles, together with regulations on how roadways are to be constructed (particularly in regards to distance between lanes, visibility, etc.) There's nothing really analogous to that with respect to guns, not with our current level of technology. Maybe a couple hundred years from now we can Westworld guns that can't fire deadly rounds except in specific conditions, but something like that is a LONG way off.

That's pretty fucking easy - there's several folks I know that wouldn't be here today if they didn't have a gun on them, or would not be here in a good state of body and mind.
I'm pretty sure that the number of lives saved by "person defending themselves or others with a legally owned gun" quite dramatically outweighs the number of dead in mass shootings, by probably at least a couple orders of magnitude. If you figure the lowball estimates of around 70-90k "legitimate" DGU incidences annually is accurate, if you said that even five percent of those were "they would have died if they didn't have a gun to defend themselves with" cases, you're still at least a full order of magnitude above a typical year's mass shooting deaths and quite a lot higher than that if we're only talking about school shootings.
Emotionally, what's happening is deplorable and it needs to stop. The very, very first step of that is voting Republicans out of power (or finding other means of removing Republicans from office but I get banned when I start muttering about those other options.) But I would really love it if people would stop standing on the still-warm corpses of children to try and bludgeon people with morality. You aren't a single fucking bit better than the shitheel Republicans that have enabled these murderers through legal and political obstructionism.
It's fucking ghoulish. Be a better person.
