Wrong signal: London’s electric cabs delayed

The roll-out of London’s electric cabs is delayed because a fault with the electrics. Not the drive system is the problem though but the fare meter that receives a wrong signal from the vehicle.

This means only one zero-emission taxi, the TX eCity, has so far made it to the capital – two weeks after rules came into force banning any other new black cabs incapable of electric driving.
