For the daily commute expect Tomorrow's World-style trains of nose-to-tail cars; sat-nav guiding the way, lane sensors keeping us on track like slot cars, distance sensors protecting us from other traffic like invisible dodgem-car bumpers. Heaven for those A-to-B drivers who struggle to summon the energy to operate the indicator stalk; hell for those of us who see a car as more than just somewhere nice to sit on the way to work.
