They reach a million miles because they're taxis, not in spite of it.

What kills the hybrids is that the kind of people who buy these sorts of "peak appliance" cars tend to be the same kind of people who'll obliviously let some critical fluid run too low. You get orders of magnitude less of that sort of behavior in taxi fleets.

I don't know if this is applicable to hybrids, but taxis attain high mileage with relatively few engine cold starts. Engine cold starts are what kills main and conrod bearings and piston walls. Taxis' bodies may be beat to garbage, the interior might be trash, but the engine and likely the transmission too will be representative of a vehicle with an order of magnitude less kilometers driven. Because they go an order of magnitude further between cold engine starts.

All this assumes proper maintenance, especially oil changes.
