for how long? more than likely you won't get yourself killed, but its not zero risk either, you should really get them done (or diy) soon, say in the next 2 weeks, maybe a month if you really don't drive much at all. I know one person who drove all the way until his were grinding metal on metal, he lived just fine but it was risky and probably cost him more to fix because of it (though idk, replacing rotors seems to be really common these days, they're almost treated as normal wear I feel like, but if they're in good shape and you're DIYing it you can reuse them)
