Definitely get a car seat!!! I can only recommend Maxi Cosy. They got all sorts of test certificates for making one of the safest car seats for infants. Don't take you child into the car in a sling or just hold it in your arms. I am shocked seeing so many kiddies here in HK not sitting in proper safety car seats but rather on the mother's or maid's lap. In case of a serious car accident your child is going to fly through the wind shield! I would NOT drive without a proper protection for my child on HK roads or not drive at all. Car seats don't cost the world. Check out mothercare; they sell them there at a decent price. Eugenes Club is way overpriced, I thought. So please, try not to save the money but rather save your child's health or life.
