BMW is on a world tour this year with a selection of concept cars that present its vision for the next 100 years of automotive development. Catering to our wildest adolescent fantasies, these cars are aggressively, almost absurdly futuristic, with this week’s debutant Rolls-Royce and Mini models exhibiting a preference for pizzazz over practicality. BMW’s own-brand Vision Next 100 vehicle is no less extreme, eschewing traditional things like a dashboard and rear-view mirrors in favor of high-tech alternatives.
