I would drive past the Tesla offices in Palo Alto and be in S. Lake Tahoe in under 4 hours. Plenty of folks who work in that area head up to Tahoe for relaxation.
A not quite four hour drive, after a storm, when folks make allowances knowing batteries don't do well in the cold... is not quite the same as living in say, Detroit. Where it is frozen consistently maybe 1/3 of the year.
