After ~20-30 years, rubber gaskets and seals and cable insulation start failing. Plastic becomes brittle, especially if exposed to the sun. How do they solve this problem?
Modularity of construction, so that rubber components can be replaced without scrapping the whole vehicle. Reducing reliance on plastic parts, or improving the ease and quality of plastic recycling, so that we can fix the exterior components without sacrificing the chassis and core parts.
I mean most things can, it just isn’t profitable…
Planned Obsolescence, baby!
That said, we might be able to make industrial scale recycling an economically efficient activity if we build more durable goods with a longer lifecycle and limit the availability of new territory to strip mine and abandon.
So much of our “cheap” access to minerals and fossil fuels boils down to valuing unimproved real estate as at zero dollars and ignoring the enormous waste produced during the extraction process. Properly accounting for the destruction of undeveloped real estate and the emissions/waste created during industrial processing could dramatically improve how much waste we produce and - consequently - how long our durable goods last.
