If you ever drive longer distances with multiple stops, how far do you travel between two charging stops, and what speed do you try to stay on?

E.g.: I drive an Opel Corsa-e, and I usually have cruise control at around 100 km/h in the winter, 110km/h in the summer, and I stop every 150-200km to charge up to ~90%. I fully expect a Tesla to be faster, but I'm curious by how much.

I have a Model Y and depending on the speed limit, I cruise at 120-130 and stop every 200kms or so for a charge. I charge till about 80% or slightly lower when I stop.
Sounds really nice, I have to say. Is it the Standard range or Long range model?
That's how I exactly roll as well with my Model Y.
I liked the points you've made. I've had the Model Y for about two years and the reason I still with it is actually the supercharger network and the ease of roadtripping. I hate having to depend on the third party charging network and having multiple accounts with multiple providers and then figuring.
The most efficient way is to travel until ~10% and fast charge to 60-70%, it takes way less time to charge in those range and it's plenty enough to cover large distances and pass multiple chargers.

I don't bother slowing down, I drive as fast as I can get away with (and safety). Except once I wanted to one-shot a long distance and put the car on autopilot behind big trucks. This way my range about doubled. In fact it's often better for range to follow the fastest biggest car, than to drive slower but with no one in front of you. Think "150kmh behind a pickup truck gives more range than 110kmh pushing air alone".

On a 800km trip that I do twice every year, I usually just follow Tesla's onboard navigation. I have ABRP [0] open as well as a backup, but typically Tesla's superchager routing is pretty good (in mainland Europe with lot's of superchagers)

It usually charges from 5~20% to 40~70%. If you're optimizing to minimize total charge time, you should aim to charge from 10% to 60%.

Do you make those 800km with 2 or 3 stops? What's your approximate travel time, how many hours do you plan for the trip, assuming there's no serious traffic jam or anything like that?
It's actually a 915km trip ending up in the French Alps during winter time, so it's more taxing on the battery. We need some juice left on arrival (30%) You can test it out yourself on ABRP [0]. My trip goes from Lier, Belgium to Les Saisies, France.

With "quickest arrival" setting, ABRP does 4 stops with a total charging time of 1h25min (and 8h29 driving). The stops are 28, 18, 18 and 22 minutes respectively.

You can do it with 3 stops, and perhaps even in 2 stops during the summer and limiting speed, but then you spend more total time charging.

I like the 20 minute stops every ~2 hours. We travel with kids so the bio-break and leg stretching is appreciated. We leave in the wee morning hours so we arrive at the destination in the afternoon and avoid some of the traffic.

That depends so much on conditions. But on family trips I usually drive 3 hours in the German Autobahn (MY) before the first stop (with a max speed of 150km/h) then ~2:15h until the next stop (as i would often only charge to 80%). Unless family wants to eat after the first stop, then we can drive another 3 hours.

You can of course also empty the battery from 93% to 8% (drove that yesterday) after 212 km when driving at max speed of 188 km/h (3C avg. temp)

Long range, we usually stop every 250km. So say I travel to Istanbul, I stop at the Bolu Supercharger station after around ~220km. It's just peace of mind and I drive a tad faster, around 120km/h.
