Whether intent is required is down to how the law is written. For many offenses “strict liability” applies, where intent is not required, they only have to prove you did it, not what your intent was.
DUI is typically a strict liability crime. They don’t need to prove that you intended to drive drunk, only that you did drive drunk.
The strict liability means once you choose to become intoxicated, you're liable for driving intoxicated, even if in some other context your intoxication would mean you couldn't form the requisite intent for something, e.g. have sex.
If there's too much distance between the act you intend to do and the strict liability acts that complete the crime, then the crime would be considered unconstitutional.
Criminal law in common law systems emerged from tort law, so there are many parallels, including the notion of strict liability. (Thus the old axiom about crimes being an offense to the king, specifically an injury to the peaceful society he's ostensibly trying to maintain.) But criminal law has a moral dimension that is absent or muted in other areas, so strict liability could never be as expansive as in tort law or regulatory law.
Fairly certain that the entire point of strict liability is that mens rea is not required for certain crimes. As in, if I meant to travel at 70 and was instead doing 100 it doesn’t matter that I sincerely meant not to speed and did not know I was speeding, I can still be convicted even if the judge believes I had no intent.
Negligence can be "unintentional" but still land you in the realm of having a guilty criminal mind.
I find it to be a reasonable take. If you're accidentally going 100 in a 70 (which is a misdemeanor in california), you're not being a careful enough driver, and we deem that lack of care criminal.
That’s just another way of saying “not all crimes require a guilty mind” with extra steps
IANAL but from what I've looked up in the last there's at least willfulness that matters for these things. For example if you could prove that happened because your car accelerator pedal broke and you had no opportunity to react, I'm pretty sure you would not be guilty, strict liability or not.
LMAO “there’s no such thing as negligence” I type on my phone as my car plows through the doors of a Black Angus
