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.
And battery safety.
They're almost certainly using LiFePO4 chemistry, which tends to be pretty good for safety.
LiFePO4 gives up some energy density. Where have you learned what is typically used for batteries in these? LiFePO4 certainly is a safe choice.
