Winter travel shortens daylight, so a route that looks manageable on paper can feel much longer after dark.
Holiday weekends tend to make both departure and arrival windows slower than the raw route time suggests.

Origin and destination are on the same clock, so arrival timing is easier to judge at a glance.
Temperature spread
