I believe the real future of transportation was launched in pre-Enlightenment France, by Blaise Pascal — he of the famous wager, that posited belief in God was a safer bet than non-belief — in the year 01662. After inventing the mechanical calculator, the philosopher turned his mind to the problem of traffic in Paris, which, with a population of half a million, was then the most populous city in Europe, and the most densely settled. The wealthy got around in private carriages, drawn by horses, which they paid vast sums to maintain. The poor walked. Pascal dreamt up a system by which “les petites gens,” the little people, could move, if not in as much comfort as the rich, then at least as quickly and reliably. His “carrosses à cinq sols” were horse-drawn carriages, each seating eight passengers, “infinitely convenient,” as Pascal described them in his appeal for a royal patent, and “leaving at regular times, even when empty.” For a fare of five sous, the carrosses carried passengers along five lines, on both sides of the Seine River. (A fare increase to six sous led to protests, and, after fifteen years, the service shut down.)
