Take any petrol car sold today and show it to a mechanic working on a Ford Model T 100 years ago and there is a fairly good chance they would understand roughly how it works. An internal combustion engine at the front turns the wheels, carrying a driver behind a steering wheel, some passengers and luggage.
The advent of electric cars changes everything. No longer will the shape of the car be defined so rigidly by bulky engines, exhaust gas handling or driveshafts. At the same time, digital technology promises to replace everything from rear-view mirrors to the human driver. Never has the car industry had to cope with so many changes all at once.
