From flying taxis to Batman-style surveillance motorcycles, Dubai’s GITEX expo this week showcased innovations that were symbols of the city-state’s ambitions to be a metropolis of the future.

Known for its futuristic skyline and artificial islands, Gulf emirate Dubai has carved out a place alongside cities like Singapore as a hub for innovative ideas.

At this year’s 37th Gulf Information Technology Exhibition (GITEX), which runs until Thursday, city authorities were keen to show off they remain on the cutting edge.
