First time i took carpool with uber I didn’t proceed as it was taking way too long, was at changi expo so I ended up taking mrt back. Second time I managed to get to use uber car pool. It was significiantly cheaper than I remembered. It was like half the price from getting your individual car uber. A second seat was also going for +1 dollar. I am travelling from west coast to havelock and it was around 7.8
