I don't think the experience will be like Tesla and Rivian at all. When you're working with a manufacturing behemoth like Magna, they have ALL of their ducks in a row. Both Rivian and Tesla are trying to build from the ground up. Magna's been there and done that a very, very long time ago. It won' be perfect but I don't expect it to be anywhere near as sloppy as what Tesla and Rivian are doing.
I don't think Magna solves the problems Rivian is having:
1) The UI system is half-baked. It's great when it works but it is a little buggy and problematic. It's an going development process and early buyers are beta-testers. Ma
2) The tonneau design is super unreliable. The first thing I said to myself after seeing it in my First Mile test last week - this will be the first thing to break. There will be some unrefined design choice I'm sure with every first gen EV.
3) Driver+ (driver assist) is problematic. It's completely built from the ground up. What driver assist system is the Fisker Ocean using? I'd feel more comfortable if they used some known open system like Open Pilot (Comma AI) instead of building their own.
4) Low part supply. Carmakers have enough parts for production but many not for EVs that need repairs.
This isn't like Kia/Hyundai who can slap a well tested Highway Driver Assist system into an EV and it works magically without problems. Heck, even the Korean EV twins still have issues.. zombie mode, blown speaker amps, misaligned panels, warm/cold-gating. These two carmakers are often top of the reliability charts and their new EVs are showing more problems than their traditional ICE cars.
Traditional carmakers struggle with EV system complexity. See the Ford recall for the HV junction box (contactors overheat and weld shut). New 2022 Bolts are failing shortly after delivery due to possible faulty contactor. There have been LG battery recalls for the Kona, Bolt, and ID.4 (not all of them though).
For an EV supposedly being released soon (Fisker One).. there's has been no public test drives of the Ocean. I feel this EV is probably two years away from "refinement" - the first year will be working out kinks. I fully realize this and will happy to see what crazy new innovative features Fisker comes up with.
