This is the right way. Building a mass market car is an enormous exercise. We have seen this with Tesla, which has thrown money at the problem and will still take 4 years to become mass market (2.5 already over + another 1.5 years). After these 4 years, its unclear what the value add will be.
Tesla has built a category from the ground up. That is a very different challenge from replicating an existing business that has gone through decades of refinement.
If anything, "replicating" (or outright purchasing) what was developed over decades is just entrenching the past. Apple succeeds as it does by practically inventing future tech and making it instant commodities (yes, they're not always first, but hit so hard and go so far they dominate first movers).
