housing project in the vicinity demanded a refund as they did not know they would have to live next to a columbarium. Responding to opposition MP Lee Li Lian's questions in Parliament, Khaw acknowledged the oversight and used the Butterfly Lovers analogy to explain how "tender procedures have not caught up with time ... the (HDB) officers assessing the tender just assumed that it must be a company affiliated to some religious organisation". The columbarium plan was eventually aborted. Minister for Transport (2015–2020) On 28 September 2015, it was announced that Khaw will be the Co-ordinating Minister for Infrastructure as well as the Minister for Transport from 1 October 2015, taking over a portfolio that has been under heavy public scrutiny. Khaw wrote on his blog that he did not volunteer for the "thankless" job, but accepted it nevertheless as he put the nation's interest above his own. A key tenet of Khaw's transport policy is his vision of transforming Singapore into a car-lite city by 2030, which includes building a "smarter, greener and more inclusive transport system". He has stated publicly that 75% of trips should be made by public transport by 2030. Khaw has also advocated for the use of driverless buses to tackle the manpower crunch. Three towns in Singapore will introduce these new vehicles by 2022. Khaw has had several run-ins with both the state and independent media. In one notable incident on 27 July 2017 at a forum on infrastructure management, Khaw stated that train reliability has improved three times since he took over. He was subsequently criticised online by commuters who had experienced persistent breakdowns in the same period. Khaw had derived his statistics based on preliminary data excluding all delays caused by re-signalling works. Khaw further berated the Singapore press for reporting extensively on the MRT breakdowns, criticizing them for "turning tabloid", "publishing frightening figures", and magnifying the problem to which he has no solution. He added that if solving the problem was as simple as "holding a pen and writing a few articles", members of the media should run the transport system instead and Singapore does not need any engineers. As Minister of Transport, Khaw had indicated in March 2017 that public transportation fares were set to increase and a fare review will be conducted by the Public Transport Council (PTC). Rationalizing the move, Khaw said that operating costs have been increasing,
