It probably has the same safety rating as a scooter. These cars aren't meant for highways, but are great for urban commutes within a few kilometers. The perfect use case is if you need it just to get groceries.
I don't dispute the use case for urban commuters and short distances, however, these things should absolutely have airbags. You can be the safest and most responsible driver, but some crazy a*hole can still slam into you head on with a SUV. Airbags should not be a cost cutting option.
