To own a car in Singapore, a buyer must bid for a certificate that now costs $106,000, equivalent to four Toyota Camry Hybrids in the U.S., as a post-pandemic recovery has driven up the cost of the city-state's vehicle quota system to all-time highs.
My mother was born in Singapore and we've been to visit many times. There are a lot of taxis, and they are quite cheap. As a tourist it was cheaper to take a taxi than public transit when we were a group of 3 or 4 people. 2 people was pretty close either way. I'm sure public transit is cheaper when you're a full time resident, but my grandparents just use taxis all the time due to their mobility issues.
