“What I am anxious people should bear in mind is that trams, railways, and ‘tubes’ by no means exhaust the catalogue of possible improvements in transit; indeed, I am not sure that they are the means of communication for relatively short distances which some years hence will find most favour. What I should like to see carefully thought out by competent authorities would be a system of radiating thoroughfares, confined to rapid (say, fifteen miles an hour or over) traffic (that is absolutely essential), and with a surface designed, not for carts or horses, but for some form of auto-car propulsion. If the local authority which designed and carried out such a system chose to run public auto-cars along them, well and good. But this would not be necessary, and private enterprise would probably in time do all that was wanted. In such a thoroughfare there would be none of the monopoly inseparable from trams, the number of people carried could be much larger, the speed much greater, the power of taking them from door to door unique, while there would be none of the friction now caused when the owners of the tram lines break up the public streets. It may be urged--and, perhaps, with truth--that at present the auto-car industry has not devised an absolutely satisfactory vehicle; but we are, I believe, so near it that the delay ought not to be material.” “It is, of course, obvious,” he continued, “that the present difficulty of locomotion in our streets is almost entirely due to want of differentiation in the traffic. We act as the owners of a railway would act if they allowed luggage trains, express trains, and horse-drawn trams to run upon one pair of rails. The radiating causeways, as I conceive them, would be entirely free from this difficulty. Neither the traffic of cross streets, nor foot passengers, nor slow-going carts and vehicles would be permitted to interfere with the equable running of fast cars. There would be no danger and no block; and as the causeway would be connected at intervals with the ordinary road and street system of the district, and would melt into that system at either end, every village in which there were enough residents who had to be in London at a fixed hour every day could have a motor of its own. It might be well worth a manufacturer’s while, I should suppose, to lodge his workpeople out of London, and to run them to and from his works.” No electrician living can predict with certainty what the motor-car may _not_ result in. One thing only is probable--that our metropolitan streets will soon be congested with vehicles to such an extent as to leave no space for horses. And then will come the complete victory of the automobile. CHAPTER XVIII _ELECTRICITY APPLIED TO NAVIGATION (A FORECAST)_ “And knowledge shall be increased.”--DANIEL xii. 4.
