tourists

Malta is ~316 km2

should be ~384k total cars according to shown table and 2019 population number (~502k )

Worth pointing out it's the 4th most densely populated sovereign entity

someone who doesn't have a splitting headache can do the rest of the math to figure out how many cars per square kilometer that is

Most people don't use their cars to drive very long distances most of the time.

Edit: also yeah there are probably lots of cars to rent for tourists.
