Brit transport pundit Christian Wolmar on why the driverless car is on a 'road to nowhere'


Re: They will never work in an urban environment.

Self-driving cars - will never be fully safe, will not reduce traffic congestion, will not reduce travel related costs, will not reduce fuel/energy consumption nor emissions sufficiently to prevent global catastrophic climate change nor take full advantage of the benefits that plug-in hybrid and all-battery EVs offer. Why are we being misled to believe this high-tech nonsense makes sense? Follow the money.

A strong case can be made that plug-in hybrids have more potential to reduce overall fuel/energy consumption than all-battery EVs like the Nissan Leaf or the Tesla. The greater problem with automobiles is their shear numbers and traffic congestion, the impacts car-dependency has on other modes of travel - walking, mass transit and bicycling, and upon the sort of economic development that does not rely on excessive long-distance travel and transport. The Tesla battery pack has 15x the capacity of the Prius plug-in hybrid. When all EVs are matched to household electricity and rooftop PV solar arrays become commonplace, PHEVs more readily complement regional utility grids, reduce the cost of rooftop solar, and offer households the means to more closely monitor all electricity consumption with the choice for household uses or for driving, whereby more driving trips shorten and become possible without having to drive. Some years back, the LA Times published an article titled "The 500 mpg Solution" to infer that plug-in hybrids have more potential than all-battery EVs.
