They even managed to beat Uber to delivering a service; although one big factor in this companies favour is SG is a small and extremely well engineered and well planned country with an extremely high level of traffic safety.
Another is although USA often claims SG is a poster child for “free market economies and deregulation” this is not strictly true; SG has a more hardline attitude to rules and regulations than Northern Europe (including DE) although by and large follows EU regulations for everything (in spite of being thousands of km away).
It also has a very high level of direct investment by govt (therefore using the taxpayers money) in private companies, to the point they could be classed as part nationalised, except the level of govt control is perhaps more subtle. (This is hard to explain and I am not an economist; although its not dissimilar to how Germany operates).
Corporate taxation is lower than Europe as the govt are at least smart enough to realise that overtaxing companies they already own and have some control of is pointless but there is a lot of pressure on startup companies there to actually deliver something useful (which by and large they do).
TBH I’d trust this service in SG way more than one in USA….
