This is a good point, which is why we exercise judgment. Pretty much all laws are written for an imaginary "average individual" because they cannot possibly account for all the wide diversity of people's mental and physical abilities, but that's why determining whether there's been a violation of the law is entrusted with a person, not an algorithm, who can consider whether there have been extenuating circumstances, and being autistic qualifies. Obviously, many laws aren't meant for people who are unable to comply with them, and every law recognizes that there may be valid reasons for breaking it.
