Source your falsehoods, half wit.

Everything but the battery is lower cost than it used to be. Lightweight cast or semi-monocoque construction, better purity silicon for lower resistance igbts & MOSFETs, not to mention very high speed switching configurations, a big deal that your low-quality ass isn't even aware of.

The motors have about 6 -15 parts nominally, at the upper end solely if they're liquid cooled.

I'm an engineer, and I'm calling you a liar in front of everyone. What the fuck are you going to do about it?

I'm thahalf wit, and you think some voltage regulators and better silicone make batteries never degrade, while every source available acknowledges a 1200 to 2000 cycle lifespan of ev batteries. You're a riot.

Particularly, the one who doesn't proofread.

I notice that you've retreated on your other points of expense in an EV, back to the only place you feel safe: the batteries. Looks like I'm winning so far.

Let's look at your remaining point: batteries.

Ask yourself some questions: what's the definition of a charge cycle? Does a partial discharge count as a cycle? Your statements suggest poor reading & critical thinking skills, not realizing that in the lab, battery life is tested by fully cycling the battery whereas in real life, people partially discharge their larger capacity devices. Phones are easy to fully cycle, their competing goals of slim, fast and large display requires a very unfortunate concession on battery size. Big batteries like laptops, vehicles don't see getting charged and drained, end to end, very often. Congratulations, you've misinterpreted scientific data the way big oil wanted you to.

Like your mind currently, a battery will eventually become feeble. Enough cumulative charge cycles (affected by temperature, being charged at level 2 or 3, etc), the battery will wear out. Here's the cool part: almost all of the lithium is extracted and purified for recycling into the next battery pack. Redwood materials was started by one of Tesla's actual OG co-founders, and they're not alone, there's ascend materials etc, whose sole focus is reprocessing batteries to extract lithium.

So your battery lasts you 10 years (with current in-field tech), and even then, still has about 70% of original capacity. Li-ion cells are currently about 85% cheaper than they were in 2010, and there's a lot going on behind the scenes I'm not free to share showing it'll continue, albeit on a more modest trend .

As the costs continue to decrease due to network effects such as recycling, your poorly sourced fears of replacement demonstrate how dangerous poor science writing can be for the general public.

Frankly I would've kept scrolling, not responding to your original inane comments but for that people actually seemed to be falling for your pompous charm and snakeoil, vs reality. That's not good for any of us, and you should be ashamed of yourself.
