> A co-worker drove to SLC from LA (abut 700 miles) in their Model 3 a few months ago. It took over 24 hours, including charging along the way, and they had to pre-plan their stops to make sure they could make each charger without their battery dying

Sorry, your co-worker is likely lying... that would mean something like 14 hours of charging per 9 hours of driving which is very far from reality. Easy way to check: https://abetterrouteplanner.com

No, they were definitely not lying, and its one of the things that turned them from a Tesla enthusiast into someone who won't be getting a Tesla ever again (ongoing issues with AP/FSD being the other).

Assuming infinite fuel/charge, LA to SLC is 9 hours of driving with good traffic, in temperate weather.

In the winter, temperatures along the way can approach or drop below freezing; in the summer most of the drive is 100+ degree temperatures. In both cases, the temperature drastically lowers range before taking AC/heating into account. This has little to no effect on ICE vehicles (except at the start of the drive when the engine is warming up) but has huge effects on EV vehicles; cold can reduce EV range by as much as 40% and the heat reduces range by about 15%. This means that a Model 3's theoretical range would only be about 200-280 miles. This means the car has to be charged at least twice for the trip to Vegas, and 2-3 times for the trip from Vegas to SLC. It turns out the charging situation is great from LA to Vegas (Barstow, Baker, and Primm) but almost non-existent past Vegas (essentially nothing past Vegas until you reach St George, hence the need to plan stops.

If you're lucky and the Supercharger is available when you need it, great.. Not so great when all the spots are taken, and you're either waiting in the cold/heat or relying on the EA station a few miles down having working charging. Unfortunately, EA stations along this route generally don't have supercharging speeds...

While in Yellowstone I encountered a handful of Teslas from Angelenos who said that it took them the better part of 2 days to get there (but otherwise weren't specific about the time, route, charging situation, etc), so it's not an isolated incident.

Long story short: just because you're a techie and can optimize your EV driving doesn't mean everyone else will. Your experience is the exception, not the norm.

I drive an EV (not Tesla) in a part of the country that is cold during the winter, there is no need to explain how it works. You can go into ABRP and change the reference consumption to 50% of the initial value and hopefully understand why no one with any experience will believe it took 24 hours to travel 700 miles on an interstate route with plenty of chargers.

> It turns out the charging situation is great from LA to Vegas (Barstow, Baker, and Primm) but almost non-existent past Vegas (essentially nothing past Vegas until you reach St George...

Both Tesla and EA have chargers 80 miles from Vegas in Mesquite? And something like 14 locations combined between Vegas and SLC?

> ...relying on the EA station a few miles down having working charging. Unfortunately, EA stations along this route generally don't have supercharging speeds...

Every EA station between Vegas and SLC has >= 1 charger at 350 kW, I don't understand what you are saying. Regardless, the charging curve for a Model 3 spends a lot of time <= 150 kW so it doesn't make a ton of difference.

> Long story short: just because you're a techie and can optimize your EV driving doesn't mean everyone else will. Your experience is the exception, not the norm.

This makes sense in parts of the country where fast charging is scarce. The route between LA and SLC is full of chargers, both Tesla and CCS. Tesla handles the routing for you, there is nothing to optimize on this route.

They do...now...They did not several months ago when my coworker attempted this drive. At least, none that were working or available.

Yes, they do. And they have on average of 0 working chargers at 350 kW, so the theoretical charging speeds are irrelevant.

Ah yes, Tesla does such a good job at routing. Just like how it loves to route cars into trucks and stopped vehicles. Just because your experience with your empty Tesla works for you doesn't mean it works for families with greater charging needs.

The Mesquite EA location has photos on Plugshare dating back to 2019 and the Tesla locations opened in 2021 and 2022. You can check https://supercharge.info for opening dates of the superchargers along the route. EA built that interstate out quite a while ago.

> Just because your experience with your empty Tesla works for you doesn't mean it works for families with greater charging needs.

I don't drive a Tesla but I also don't understand what this means. The route has superchargers and EA chargers all over, damn near perfectly spaced out, and the navigation system includes them in routing. If your coworker took 24 hours on this route, it was not caused by driving an electric vehicle. Again, you can use ABRP, modify the variables, and check for yourself: it is not possible to get anywhere near that amount of charging time on that route regardless of conditions.
