We have this booster seat for our daughter (4.5 J 16.5 kg) brought before the holiday to provide them with to take on vacation. So you do not depend on destination of the journey on the local availability in the taxis. I can only recommend that at our destination in Asia no driver as a safety component was carrying. The booster seat is very light and yet stable. The straps go through good and armrests prevent slippage. This made the taxi driver locally markedly reduced possible.
