As other commenters have mentioned, personal car ownership is very much dis-incentivized in Singapore. It's a city-state so walking, biking, and transit are where it's at.

More transit. It is a tropical city state, so walking and biking any amount of distance outside isn’t very pleasant during the daytime (and will require a shower and change of clothes if going to work).

Singapore really disincentives the usages of cars. Which is understandable when you have to cram 5 millions peoples on 722km2. Car, and especially car infrastructure take a lot of space. It is something you can afford when you have the space of the US or Canada, but when you are a small city states, public transportation makes a lot more senses.
