When we originally posted about this it was big news. Now many of the leading car manufacturers have a vehicle that will drive on sensor technology!

If you think that a car having fully automatic controls and running on a dedicated electric highway like TEV is a big technical challenge, here is a normal BMW 3-Series – a production vehicle – going around the Laguna Seca racetrack in California at high speed without any input from the driver at all. The special electronics control the car in 2-dimensions (speed and lane changing) which makes it vastly more complicated than the straightforward 1-dimensional system required for TEV Electric Highways (no lane changing). Far from being science fiction, the simpler automatic control technology required for TEV vehicles already exists. Watch the car go in this Sunday Times InGear special (Youtube)
