Car ownership in Kigali is low, with just six per cent of households possessing one as of 2011. Most residents therefore rely on public transport for journeys within the city and elsewhere. Historically most passenger journeys within Kigali were in minibuses, operating under a share taxi system with sixteen passengers per bus. In the 2010s these were phased out in many areas of the city, in favour of larger buses, some of which permit cashless payment through a "Tap & Go" card and online bookings. Motorcycle taxis are a very popular form of private-hire vehicle, with 10,486 drivers registered with cooperatives or syndicates in 2012 - a figure which is likely an underestimate. The government has announced plans to replace the country's fleet of petrol-powered motorcycles with electric vehicles, and online booking and metering has been rolled out for both motorcycles and taxicabs in recent years, such as Yego Cab and Move Ride by Volkswagen. Bicycle taxis operate in some areas of the city, being reintroduced in 2014 after a period in which they were banned.
