The suggested hypothesis is that people take at least a day to recalibrate their driving behavior in light of new snow.

Solution: make an explicit effort to avoid driving on the first snowy day after a sequence of non-snowy ones. Use Anki to remember this association.

What, one can recalibrate one's driving behaviour in snow without actually driving? If not, not driving on the first snowy day only means that you'll get the effect of increased risk on the second snowy day instead. (But on the other hand you'd still be less likely to be involved by accidents caused by others -- but such a rule is not Categorical Imperative-izable.)

Aren't there stable rules which are perfectly Categorical Imperative-compatible? Thinking in UDT sort of terms, perhaps the rule would be 'flip a coin to decide whether you start driving on the first or second day'. If everyone did that, half the population would drive day 1 and half day 2, which seems superior.

Huh yeah, it would. I had forgotten that in such cases good strategies can be non-deterministic.

Well, it's not just in 'such cases' but in tons of games there are mixed strategies and even mixed strategies which are the Nash equilibrium.

Well... by such cases I kind-of meant "several-player games". (Then there is the absent-minded driver problem... maybe if you count the driver's self before and after the first intersection as different players... but then that becomes a variable-number-of-players game. Whatever. I guess I've just internalized way too much.)

Other drivers causing accidents is a major problem. But also you should put in some effort to update your own driving. In general I would say: do not drive while problematic drivers are abound. That means weekend nights, and the few days with severe changes in conditions.

That means weekend nights

Exactly the time when alternatives to driving are the least available.
