The $54 fuel cost is a good estimate, but always keep an eye on your gauge, particularly before heading onto less populated local roads. The "turn-heavy local drive" profile suggests having your navigation system or maps readily accessible to manage the numerous directional changes.

Seasonal Notes
Summer travel usually means heavier construction, hotter rest stops, and busier weekend traffic around major cities.
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.
Time zone
Origin and destination are on the same clock, so arrival timing is easier to judge at a glance.
Temperature spread
A meaningful temperature swing is a good cue to rethink layers, water, and how soon you want to arrive.
