I'm not sure how to parse your word-salad.
You do know that cars today are made mostly from aluminum -- which is almost 100% recycled. There's steel in there, too... which is also almost 100% recycled. EVs are currently dependent on Lithium Ion batteries. Pretty much every electronics store not only has a recycle bin for mobile electronics, but encourages you to use it, too. Why? Well, sometimes they're legally required to... but Lithium Ion battery recycling is the best thing since sliced bread to manufacturers who use them in their products. Ever crack open one of those iPhones or Samsung Galaxies? Most of what's inside by mass is the Lithium Ion battery. Recycling them isn't difficult. Do you have any idea how much cheaper it is to just re-use aluminum, steel, and lithium rather than dig it out of the ground as a raw material to refine?!?!?
Teslas aren't made to be replaced every 3 years... most electronics aren't -- just phones and tablets as they evolved quickly... and they're just now starting to extend their expected lifespans. Computers used to be the same -- new every 2 years for every business... then every 3... then every 5... now, lots of places have 7 or even 10 year old PCs running Windows 10 just fine. The TREND is the opposite of what you describe. New technologies evolve fast, older ones tend to stagnate and flatten out growth curves and create longer-lasting products.
Teslas have fewer moving parts and fewer parts that need maintenance, so your basic gasoline powered car has more throw-away parts. The Tesla's biggest expense and liability is its lithium ion battery packs... which they're improving & by entering the Li Ion battery business, they have a stake in improving the batteries and lowering their costs -- which will include recycling the lithium from the old batteries eventually as well. There's no reason a Tesla couldn't run for decades just fine with only swapping out older battery packs to be recycled and replaced with new battery packs.
Further, the USA has barely scratched the surface of its mineral resources. We have confirmed rare-earth metals and lithium deposits we aren't touching -- because China is mining away just fine for cheaper than it'd be worth for us to bother... especially considering the environmental impact of mining in our own back yards. There is no shortage and no future shortage in sight -- just corporations staking claims to get the largest control over the current sources of raw materials... which is no different than any other time in history. If and when it becomes worthwhile, we'll dig for our own and make our own refineries.... but, more likely, we'll recycle what we have first -- just like with aluminum and steel... and to a lesser degree, copper and other precious metals. We do mostly send our electronics recycling (other than lithium) to China... where they use a nasty process to extract gold, palladium, platinum, and other precious or rare earth metals from motherboards. It's become more profitable to get some of those metals from electronics than from raw ore in mines already, too.
