Are you joking?
The kinds of electric motors that go for decades with just a couple pumps of grease are reserved for industrial applications because their economics doesn't make sense for consumers most of the time.
I like my cordless drills and grinder but I'm not delusional enough to compare them to industrial motors that are twice (or more, they tend to have massive cases) as heavy for the power output and live for decades. I have a 15hp motor kicking around that dwarfs a Tesla motor in every way except output. That kind of stuff is monumentally inefficient for any non-stationary use.
3yr and you're done sounds about right for consumer battery degradation in hard use. How long a battery lasts is basically a reflection of how nice you are to it in terms of charge and discharge cycles and how much reserve capacity you want to tote around.
We've got electric motors pretty much down and can build them for just about any use case but for a given longevity vs power output batteries are still pretty bulky for the output you get.
