780 Mile R2 Road Trip - Comfortable Ride, Problematic Software, Frustrating Data

[VandalSibs]

You mentioned paying $12.99/month to get a Tesla Supercharger discount = regular Tesla driver rates. Did you notice whether the charging speed was close to the rate at which a Tesla charges for that fee, given that you stated you owned a Tesla Y RWD for a short time? I didn't know that non-Tesla vehicles are charged 25-30% more than Tesla owners at Tesla Superchargers.

The charge rates/speeds are not dependent on being a subscriber to Tesla's membership or not. They are entirely a combination of what the vehicle can do and what the charging station can deliver.

I read on another thread (I don't know from personal experience) that Tesla V4 SC limit non-Teslas to 500KW, even though capable of 600KW. Really only affects R2 for a short period of charge time.

Here are the details of the R2 sitting for 84 hours in a garage with 80% charge.

...So after 84 hours (3.5 days) in a garage with temperatures in mid 80s unplugged. It went from 80%-78%, battery reports 91.4 kWh so it used 1.83 kWh.

Now we're getting somewhere... that distills down to just a tad over 0.5kWh/day and about half of the R1 vehicles daily loss.

Thanks very much for running the test and posting the results @SANZC02

Non-Tesla vehicles are limited to 500 amps when using superchargers. Tesla vehicles (3/Y) can pull 600+ amps for a short time when using superchargers. There is word from Tom at StateOfCharge that Tesla will remove this cap at some point, but no one knows when. You will not notice a difference in charging speed on R2 unless you are paying attention, plug in at a low state of charge, and comparing the speed to an Alpitronic unit.

Btw, you compared Tesla Autopilot to Universal Hands Free on the R2. Tesla never offered Autopilot on the 2026 Model Y RWD, the base model. Tesla only offered Traffic-Aware Cruise Control (adaptive cruise control) in those vehicles. The lane-centering Autosteer portion was omitted from the base package, so owners seeking automated steering or lane-keeping features out of the box must rely on the Full Self-Driving (Supervised) software package or a subscription.

Comparing Tesla's Adaptive Cruise Control to UHF is complete apples and oranges. Since you said you never used the FSD, then you would have realized just what it can truly do if you had. I realize Rivian will catch up, as Tesla's early FSD was not very good. But until that happens, UHF isn't close to FSD, but certainly better, I guess, than adaptive cruise control only.

A majority of the chargers I was charging at were Tesla 250 kWh superchargers. The final charging stats showed the R2 would peak around 190-195 kWh, and then by time the charge was ended it typically averaged around 180 kWh. I only charged at 1 V4 supercharger and did not notice much of an increase.

Tesla did offer Auto Pilot on the RWD Juniper. I bought mine in May or June of 2025, the Standard edition did not come out until October of 2025. When I bought it I could only choose from the Long Range AWD and Long Range RWD. Auto Pilot did not get removed until January 2026. I had what is now called the Premium RWD, these shipped with Auto Pilot.

Both cars came with trials of FSD, I'm aware of the capabilities of FSD and the experience.

Just to be clear, I didn't say UHF was comparable to FSD. It is however comparable to Auto Pilot, and in some ways is better than Auto Pilot, and the opposite is true as well.

Not having to have your hands on the wheel is a much different experience than Auto Pilot constantly reminding you to touch the wheel. The trade off is UHF gets upset very quickly if it thinks you're looking away from the road.

UHF also struggles with sharp curves, I'd say it disengages nearly 50% of the time in this scenario.
