Welcome. I see lots of Lucids these days around Scottsdale.
Interesting post. I just asked Google's AI what it costs to drive the 2400 miles if electricity is 20 cents per kilowatt hour and the car average 4 miles per kilowatt hour. It came to $120. i asked a similar question on an ICE vehicle assuming $3.50 per gallon gasoline and the car is getting 24 miles to the gallon and it came back with $350.
But, on this trip one would not be charging at home. So assuming 50 cents per KWH at fast chargers, the answer would be $300. Of course, this answer ignores other costs (depreciation, oil for an ICE vehicle, battery degradation for an EV, etc.) but even at that cost it is less expensive than doing the same thing in an ICE vehicle.
I did the original calc because I thought it would have been more expensive for you to travel all this distance and wondered if you were really saving money but it looks it was not that expensive.
I drive from Phoenix to Las Vegas or San Diego or Los Angeles and return but that is as far as I am willing to drive. You are a trooper.
