Some say that renting a car is more affordable than owning a car, what about blueSG/(other car sharing platform)?

Factors to lookout for

1. Excess to be borne if accident (any options to reduce CDW?)
2. Able to book easily, many cars around
3. location of end/start trip (For bluesg) and number of hours required (for point A to A)
4. Petrol (self pump to pay, any minimum amount to pump or mileage wise cost)
5. Timing of the booking (which affects car traffic, ERP to pay, parking availability)

Bluesg excess very high
