Of that I have no doubt. I have seen how crazy surge pricing can get at times. Uber needs competition to keep it honest, but in the end, ride-sharing is a winner-takes-all scenario where there can be only one.
But knowing Singapore's government, they will definitively step in to prevent such a scenario, especially when Temasek owns SMRT. PAP will never allow a foreign company like Uber to control such a critical aspect of Singapore's transport infrastructure.
If I am not wrong, Temasek invested in Grab during their early days. Not sure if they withdraw already or not.
I do agree with you that they will not let a foreign company take control of the transport infrastructure. but some of the bus package are operated by foreign companies.
