I read this yesterday. Eye-opening stat "Back then, they advocated for reducing our “unbearably large car fleet” which even now consumes 24% of total import expenses "
The IMF does want us to downsize our spending on vehicles. At the same time the IMF of course will not as a principle support import restrictions on any goods. I think Sri Lanka might want to explore other ways to control - including taxes, maybe a system like they have in Singapore etc. Of course the 'proper' way to reduce this is by having a better public transport infrastructure, which will take time to properly implement. As someone who personally tried my level best to utilize public transport for several years (I tried different options to commute to work including using the railway, which was extremely unreliable, park-and-ride : drop my car at the city entrance and then use those big red buses by micro) found out, the public transport here is terribly terribly crappy. After half-a-dozen years of trying I eventually gave up.
Having said that, Sri Lankans as a people, have an American-like obsession with personal vehicles. So I doubt that even (hypothetically) better public transport availability will discourage more vehicle imports.
