Other suggestion: Check your tire pressure before starting to drive for the day. It's important to check when the tire is cold since the pressure will increase as you drive and the tire warms. Even the morning sun shining on a tire raises its pressure slightly. Tire pressure has a huge impact on range (and traction, handling, and tire temperature).
Back when I used to aggressively hypermile a LEAF I would use pressures well above what was probably safe. That reduces traction and I do not recommend it, especially on our heavy cars, but being just 1-2psi low on one tire will have a measurable impact on efficiency.
I look forward to seeing the outcome of this test.
EDIT: I forgot to mention wind speed. Try to find the local wind speed and direction for the beginning and end of your ride. Driving 75mph into a 15mph breeze takes almost the same energy consumption as driving 90mph. That same breeze as a tailwind might make one think they are a master of hypermiling.... until they head back home in the opposite direction.
Really? The irony here is too painful to pass up---Lucid's value proposition is basically
1)Fabulous design (I agree)
2) Best in class range
3) Near best in class handling
4) Near best acceleration
But from all the talk here, in order to get within even 80% of #2, you have to give up #3 and #4---put it in cruise control a 69 mph and hope for the best?
The CEO says Lucid put an end to range anxiety---read this whole thread and see if you agree...(better if no A/C; better if ACC; better at the right outside temp; better if you don't drive aggressively(that's why I bought it); better at perfect tire pressure; better if you drive downhill...check the wind direction before you leave...?
This is the end of range anxiety?
I might still buy a Touring if, when my number is called, the software glitches seem under control --- but I will buy it only for reasons 1, 3 and 4 above, and not because I can rely on #2...right now the Lucid is a beautiful novelty ---for dependability I will park an ICE in the same garage.
