Automakers, in quick succession, have moved in recent weeks to end parts of their operations in Europe. Nissan is the latest: On Tuesday, it confirmed that it would cease assembling Infiniti cars at its plant in northeast England.

The moves, during Britain’s wrenching debate over its departure from the European Union, known as Brexit, have raised the question: Is Brexit forcing the carmaking industry out of Britain?

It’s not quite so simple. Traditional car manufacturers, in Britain and in Europe over all, have been buffeted by forces around the world, and they assess where they want to make the next model of a car every few years or so.

As automakers allocate resources, they have been balancing the need to respond to these changes with the justifications for producing cars in places like Britain.
