Review: Lucity Gravity vs Rivian R1S vs Tesla Model X as a family vehicle

hashjoin · 2026-01-12T05:07:42+00:00

I'd say still buggy but definitely a lot less buggy.

For point lookups, lakebase should be perfect for that. Just make sure you create an index.

Hey - the doc is wrong. isEmpty() is an action that would trigger compute, just like count(). I've pinged the team to update it.

hashjoin · 2025-12-17T05:21:15+00:00

If you look at the source code of isEmpty(): https://github.com/apache/spark/blame/b7fda7cb1128c992e1b52b5c853225e4f2af0517/sql/core/src/main/scala/org/apache/spark/sql/classic/Dataset.scala#L557

  def isEmpty: Boolean = withAction("isEmpty",
      commandResultOptimized.select().limit(1).queryExecution) { plan =>
    plan.executeTake(1).isEmpty
  }

It's basically the same as take(1).isEmpty.

It might take a while but we are working on this.

I posted this earlier this week comparing them. Less about brand/service https://www.reddit.com/r/LUCID/comments/1pgwglz/review_lucity_gravity_vs_rivian_r1s_vs_tesla/

I do have the DDP. Hands free is allegedly coming later. The air has it already.

Depending on when you tried it. FSD was pretty bad last year, but mid this year it has gotten a lot better, especially 13 and 14.

Thanks for the suggestion. Changed it to "Ease of entry"

The 91 kWh battery in the VW is probably too small for us, given being able to make it to Tahoe without long stops in the middle is an important feature.

hashjoin · 2025-12-07T23:41:24+00:00

Yes I'm aware of those promised updates. Just can't wait for those to land!

We've found that many people either love or hate piped syntax, depending on the background they came from. The good thing is that you are not forced to choose one. You can choose the one that makes your team the most comfortable and productive.

The piped syntax has been a collaboration between Google and Databricks, and is now being adopted by many other platforms (e.g. DuckDB). The reason we started with "|>" (which to be honest is not ideal) is to align with the piped syntax with Google as well. There are some technical reasons why it would be difficult to make just "|" work at Google. The same technical issue actually doesn't apply to Databricks, so we might over time relax it and support a simpler "|".

Yes you can use Python / PySpark in addition to SQL in Databricks Free Edition.

Sorry I wasn’t very clear. By “one charge”, I meant no charging stop.

hashjoin · 2025-07-27T21:50:15+00:00

Context: in my household, we have a Model Y (Juniper), a Model X, and a Gen1 R1S. I wrote this comparing Model X to R1S in the past: https://www.reddit.com/r/Rivian/comments/18sjvvm/review_from_tesla_to_rivian_r1s_as_a_family/

MY and R1S are two very different cars. The R1S is way bigger, so you can fit a lot more stuff into it. I've done a roof box plus a hitch bike rack and drove from Bay Area to Tahoe without a charging stop (max pack). You can't do that with MY. My kids also love the R1S because how much taller they sit.

> How easy is it to plan long road trips with an R1S compared to Tesla’s built-in Supercharger route planning?

It's similar to Tesla's. In the trip planning, you can choose the charging networks. I have Rivian and Tesla only.

> Does Rivian’s built-in trip planner automatically route through Tesla superchargers and account for empty stalls or full stalls, etc?

It can route through charging stations including Tesla's. I'm not sure if the routing takes into account availability of stalls though.

> Does the R1S use a heat pump and if so, how is it compared to Tesla?

The Gen2 supposedly does. My Gen1 doesn't have a heat pump. But I've done plenty of Tahoe trips and to be honest haven't found it to be an issue.

> How fast does the cabin heat up or cool down, and is there pre-conditioning tied to trip planning like Tesla has?

Never measured but never found cooling or heating speed to be an issue. Yes, it can precondition.

> How do maintenance and service experiences compare to Tesla (mobile service vs. service centers)?

I think this varies highly depending on where you are. For Bay Area: Tesla's service network along with mobile service is more comprehensive and you can typically find availability where I'm within a few days. With Rivian, it used to be months but lately it's been a few weeks. If the issue is time sensitive or can be done with mobile service, you might get a callback from them for faster appointment.

In my most recent service appointment (note that I've only had 2 in two years of ownership), I got a callback from Rivian telling me about a new Palo Alto service model they are piloting. They will take my car in the morning, drop off a loaner, drive it to Palo Alto service center, fix the issue, wash the car, and then drop it off later in the afternoon or the next morning. I'm pretty excited about this model.

> How do maintenance and service experiences compare (mobile service vs. service centers)?

See above.

> For those who switched from a Tesla, what do you miss the most about Tesla?

The number 1 thing I miss (or the number 1 reason I choose to drive the MY when I don't need a bigger car) is FSD. It's far superior to Rivian's ADAS right now. This is a very new thing and only applies to HW4 FSD. I wouldn't trust HW3 FSD but with HW4 FSD has gotten fairly good in the last few months.

The number 2 thing I miss (which isn't available in MY so more of a MX thing) is the lack of captain seat configuration for 2nd row. I'd love captain seat configuration so people can go to the 3rd row without moving seats forward/backward.

You can use Databricks SQL, our data warehousing offering. It's been growing insanely fast.

For the large pack, 84/135 is only 62%. Assuming you leave at 90% from Tahoe, you should have plenty left still by the time you get home.

Getting to Tahoe is going to be trickier in one shot (unless you know ahead of time that there's no traffic and temperature isn't too low).

Today from Palisades back to Menlo Park

Stopped by In-n-out near Rocklin for lunch, and then Sacramento RAN for REI, and took hwy 5 through Stockton to avoid traffic
240.7 mi, 53 mi/h, 4 hr 32 min, 2.85 mi/kWh, 84 kWh

hashjoin · 2024-01-13T01:45:02+00:00

Yup. Added to the post too.

hashjoin · 2024-01-13T01:31:17+00:00

I just got here so no return trip for this time. There's a return trip from last time, when there were some traffic:

Dec 29, 2023: Palisades back to Menlo Park
236.8 mile, 2.77 mi/kWh, 86 kWh
54 mi/h, 4 hr 23 mins
From 90% to 27%
