Funnily enough, the Rivian CEO talks about exactly that in this interview

In that scenario, we would be using one ECU to do everything I just described. In this case, it’s a much larger computer, but one computer. It’s a massive simplification for how we think about software development and also drives a lot of cost out of the vehicle because instead of 70 to 80 little boxes — little computer boxes with wiring and connectors and everything else — we have, in our case, seven.

So when one small thing stops working, you now have to buy their proprietary, expensive ECU instead of a cheap little microcontroller.

I suppose I'm shilling here, but check out rockauto.com for car parts. They carry an insane number of car parts for basically wholesale prices. A lot of times you can still buy the individual parts instead of entire assemblies.

If you make sure to not charge the battery to 100% all the time, the battery of an EV will easily last for 300,000 km. There will be a slight reduction of overall capacity, but nothing that will impact your day to day life (unless it consists of driving 24/7). Overall, EVs are way more robust than ICE cars.

But yeah, if you're out of luck, then repairs are expensive because of the reasons you mentioned.

Any new automobile manufacturer has to do that initially in order to make enough money to get the manufacturing and supply chain developed enough to create a car for the masses. They start with a lower volume and higher priced car to get the excitement for the product. Once they have that, they are able to start assembling a larger volume at a lower price.

Uh... Yup. That's pretty much what I said!

I've never looked up the price. Someone should say what they cost for those curious enough to wonder but lazy enough to not look it up. I offer them one vote of approval redeemable nowhere.

Why would it be considered a toy? Actually asking
