Weird Maps Behavior - Taking me a Longer Route

[Eric_partman]

I went on about a 6 hour road trip (total time, not travel time, it was probably 350 miles or so). The last hour and a half stretch of my trip is a route I take all the time so I didn't need the GPS but kept it on so I could see how many miles I'd end home with (I was cutting it close).

This last stretch of my trip is almost all highway miles. Basically the same highway, then I live like 10 miles off the highway on back roads. For whatever reason, my GPS kept trying to take me off the highway sooner than the exit by my house. It tried taking me off 3 different exits. Each time when I ignored it, it took about 10 minutes off my drive. After the last time it did it, my ETA was quite literally 30 minutes quicker than the first route it tried to take me. Anyone know why that could be? I'm wondering how much of the other portion of the trip where I wasn't familiar also took me a longer route.

The only thing I could possibly think of is that I was pretty low on mileage. My ending mileage on the route the GPS first recommended was like 21 miles, but staying on the highway on my route got me home at like 14 miles - really not a huge difference and not nearly close enough to 0 either way.

Not weird at all. There is a setting in Google maps to prefer the more efficient route, at least there is in the phone app. Maybe there is in the new Rivian nav, or Rivian has decided to universally apply this setting.

I don’t think I have the updated maps yet. But why would anyone want more efficient to be the default vs the quickest time?

So they can make it to their destination without running out of juice.

Maybe the highway route is boring.

I just can’t imagine a situation where anyone would rather get to their location 30 minutes slower to end with an extra 5 miles of range when both ranges were above 10 miles.

When that range difference means getting to your destination. Not every drive is a nice warm and flat interstate with chargers every 50 miles. Some drives are subzero, over mountain passes, with that 5 miles being the difference of you calling your in-laws to pick you up because you thought it was a good idea to take a road trip through Montana mountains during an Arctic blast, and you only have heated seats on to eek out every mile you can...

But it’s telling me I’ll arrive with 16 miles which isn’t going to be a huge change in the last 30 minutes of a drive. And also why would they use an extreme example like that anyway? It makes 0 sense.

Sometimes Rivian really wants you to take a particular route for some reason. I deal with this quirk when setting an initial route sometimes. I know which way I want to go, but I like to have the nav running to see traffic and eta.

I realize it's a different issue than yours, but just in general, sometimes the routing can get frustrating, although I do like the Rivian nav overall.

I 100% believe that this is a low-confidence issue given your mileage. I think the nav recognized your normal route would get you home at 5%, so to make sure it doesn't strand you, it wanted you to get off the freeway and drive 30-45 MPH instead (essentially giving you an extra 7 miles of range).

If it was projecting you to arrive with 10-15% on arrival, I'm confident it would've kept you on the freeway from the get-go.

Options are unimaginable? Yet those who want CarPlay continue to criticize Rivian for not allowing options?

Quite strange. Send your feedback to Rivian. Mobile app, scroll to bottom and tap “share feedback”.

OP I had a similar issue yesterday. Left with about 53% and the GPS said I would arrive with 27 miles of range. About 30min left of my route, it wanted to take me off of the highway. I'm assuming this was suggested as the vehicle will get better milage on the streets with stop and go traffic. I ignored this as well as I was confident I would get home with milage to spare.

I reached with 9% and 26 miles of range, and I avoided the longer, street suggested route that Rivian planned. Note I'm on 2025.18 still

There is a setting that allows you to set how much range you want at your destination. If your arrival range is lower than that setting it will always try to route you to a charger to juice up so you can meet that minimum arrival range.

That’s what it sounds like to me.

 

[RivAW]

Same people would complain that nav showed they would arrive with 5 miles of range left, but didn't make it and got stuck....and would blame Rivian....

 

[BCondrey]

Two things. First, when this has happened to me it has been because of a backup or delay on the route I would have taken. That happened to me yesterday. The route looked way longer, then I figured out a stretch of road had a huge backup.
Second, the difference between 14 and 21 miles is going to force the nav to take the route that gets you there with the most miles. I think optimizing time-based routing is out the window at that point. That is way beyond most of our comfort levels.
