You hear this all the time. There is no such thing as a huge lead in automaking. It’s an incredibly clonable product, and each company has huge teams taking apart each others products.
It’s also not really the product that matters. It’s service centers, parts, repairs, manufacturing capacity. The traditional companies have entrenched supply chains to get parts, and cars, across the country and into hands. All the new companies have to build that from scratch. Producing a couple of something great is an achievement, it is not a lead.
It is much much easier to catch up on the product side than it is to innovate. And because the actual product is only a portion of total value, the companies that are “way ahead” with the most futuristic cars are really the ones playing catch up.
