That's absolute nonsense. If it's so easy, why did it fail?
It failed because there are dozens of IC (internal combustion) powered vehicles that provide better transportation for their buyers. They get owners reliably to their desired destinations comfortably (they give heat, air conditioning, cushioning, and adequate space) and safely (they have adequate range, fuel sources, reliability, and crashworthiness), and price for their owners.
Dyson obviously couldn't compete. Let him make hair dryers, they're "easy to make".
Hammer. Nail. Head.
Low production cost makes it easy for new manufacturers to enter the market and destroy the value of your investment. Dyson’s approach of high quality and technical excellence also led to an impossibly large accumulation of sunk costs that could not be recovered.

Yes, true today, but not in the coming years.
The majority of todays automotive R&D is going to EVs.
The Yaris and its kin will be around for many years.
Mid-price will go EV.
