It would have to be a whole host of legal ambushes in every market Ineos is about to sell into. Not forgetting Ineos has challenged and been challenged in various markets and already won the right to sell the Grenadier.
I think there are still various outstanding cases (at last time of checking some months ago) involving JLR and Ineos around the world ~ Portugal, South Africa & USA being 3. USA sales were conceivably put off in part due to the legal situation. Portugal has no official retail partner to date. South Africa seems to be the only one moving forward, so maybe the case was resolved there.
I think there's plenty of scope in the software issues (and we know of issues with electric/electronic gremlins), together with quality issues with parts, production line quality issues, certification, and registration to have created the current delays.
