Cab.io, well-known for their “slim cab” concept, have launched in London and Melbourne simultaneously. The all-electric, self-driving taxis are less than half-a-lane wide, which Cab.io say will mean a great reduction in traffic congestion.

The unique seating arrangement has two passengers facing each other, with their legs directed to either side. A premium “plus” service will be available for passengers who prefer a solo journey. Cab.io deny that this is a surcharge for larger customers.

The services are a collaboration between local government bodies, Cab.io and Passport XYZ.
