We have 75-85mph speed limits down here.

In order for the Lucid Air to achieve its EPA range it has to drive 47mph

You mentioned couple days ago about your 100+mpge but I look at overall range. Example the GM has a huge battery but it has impressive range despite it being inefficient.

IMO that is the wrong way to look at it when it comes to EV's. To me, efficiency is more important than just slapping in a giant battery, which adds weight (which creates inefficiency) and expense, which is why the GM trucks are so heavy and expensive. Otherwise just stick with ICE if it's such a concern. Again, just my opinion

You leave out that the EPA estimated range is over 500 miles. Lucid Air Tourings will get over 400 miles of range at those speeds, which is plenty.

Big GM EV SUVs being inefficient is no different than big GM ICE SUVs being inefficient. They make up for it with huge batteries, and in their ICE models huge gas tanks

Large battery pack and large fuel tank are very different given the vast difference in energy density. No ICE vehicle has a significant change in efficiency due to fuel tank size.

It's not just the inefficiency, it's the weight. Imagine carrying a Corolla in your truck bed, which is about what a 200 kWh battery weights

But sometimes having an “efficient” battery with shorter range may not be as time efficient having a bigger heavier battery with longer range right?

Example, I would rather charge once reaching destination rather than charging before reaching my destination. But I don’t want to sacrifice and drive under the speed limit to do so. Because correct me if I’m wrong even with the smaller more efficient battery, it suggests you to charge enough to get to either next charging stop or your destination whichever comes first.

Yes, but are you really that much in a hurry to get to your destination? Remember, for regular driving you don't need to stop to charge, it's long trips, and it's usually no more than a 10 minute stop. If you are driving 400 miles for example, you may get to your destination 30 minutes later over a gas car. If saving 30 minutes is a big concern, than an EV is not for you

From the article

We fit a curve to our data, to be able to estimate what steady-state cruising speed aligns with each vehicle's EPA range figures. For the Lucid Air, it's a mere 47 mph to achieve its 419-mile range figure. But the window-sticker number is a combined figure, and—although it doesn't appear on the label—there's also an EPA highway figure. For the Lucid, its 410-mile EPA highway range matches a marginally higher cruising speed of 49 mph.”

Are we talking about 2 different cars? I was referencing the vehicles used in the article.

Yeah, I guess we are. To me that's not a big deal, and certainly not a deal breaker

If the car delivers the performance I want, what do I care what it weighs?

I would rather not stop if possible. Whats wrong with wanting to save the 30 minutes AND wanting an EV? The long range of those vehicles is a huge selling point to me.

You've made the same point about 500 times, range and driving for 8 hours straight is the most critically important thing ever. Stopping to enjoy life for even a few minutes is a crime.

Absolutely nothing. For me I have no issues making a 10 minute biology break and stretching my legs to charge. If someone wants a truck that weighs as much as Godzilla, and costs as much as rebuilding Tokyo, go for it

But even when you stop to charge, you’re not stopping to fully charge, wouldn’t you rather bypass that stop and make it to your destination then charge?

My friend took a Google estimated 10hr drive (I don’t remember exact miles) in his model Y LR when he first got it and he said it took well over 12-13hrs. He said he would never do it again. The charging stops opened the door for unplanned snack and “guess I’ll try” bathroom stops.

My friend spends a whole bunch of time sitting in a waiting room waiting for their gas car to be maintained and repaired.

I agree
The answer is, no, I don't need to fully charge or bypass supercharging. Even when I drove gas cars where I didn't have to stop, I always made at least two stops. So I am extremely happy with my current situation. As I said and I will continue to repeat, if that's not except able, stick with ICE or get an EV with a GIANT battery. Ask me again, I'm going to give you the exact same answer
