2027 R2 Performance vs. 2026 Model Y Performance - highway efficiency test (Out of Spec comparison)

[Rivian Roamer]

Any way to delete data from certain days in North Carolina from the list, so it doesn’t skew the results?

I'm not doing that lol, that's a lot of effort for something that won't matter in a few days. I'd need to be chasing down that constantly, how do we know others people aren't just doing constant launches?

2,500~ of those AS miles were RivianTrackr. They were hard miles, including track time. Still a small sample size to infer any expectations from.

What are the thoughts of adding a break down of each driver to see the ourliers in their class?
Secondly can averages be added to the Offroad tires and Street Tires to show average speed, elevation change, etc?

Are you.... are you seeing into my future?

I take security and privacy seriously. If people want to share their individual stats, that's up to them.

Maybe I am missing something. You show drivers on scoreboards? What would be the difference here?

Also Maybe just show the worst, best, median for each tire and no user data. That way we can understand the spread.

Because people opt-in to an existing social feature for that, nothing about that opt-in says anything about individual drives.

Let me ask this differently, what data are you hoping to get at?

I think seeing atleast the best case and worst case for each tire. We already have the average.

Thats all ,and thanks for the clarity!

The issue is that best and worst are going to be impacted by far more than the tire itself. Weather, elevation, speed. The best and worst for both are likely going to look the same.

However (and this is why I ask what you're trying to get at) perhaps confidence bands including percentiles would be more helpful.

I don't see how that would be helpful. There are lots of reasons for best and worst efficiency that have nothing to do with tires. What matters is how you drive.

The best way to compare tires is with back to back long drives with as many variables controlled as possible: same weather, same speed, same time of day, same truck configuration, etc. Like @Budman does it.

Comparing results from different trucks in different weather driving in different ways at different elevations means almost nothing. And that is what you are asking for.

I might have missed it but after Kyle shredded the 21" tires drifting on their track, did they swap Jose's 20" set back on the car for his drive back to Florida or did they buy more 21" tires?

Jose put the 20s he originally ordered back on the R2 and drove home.
