The article doesn't really seem to back that up. Lots of the people pushing that theory are definitely alt-right types, but when the article doesn't present any facts to contradict them it doesn't make it seem like they're actually wrong. For some "conspiracy theories" it can be impossible to prove someone wrong, but there should be some pretty straightforward statistics to help figure out if this is bogus or not. FWIW it seems to be a commonly held belief by South Africans. The ones I know told me that in SA they won't stop at a red stoplight ("robot") in certain areas. The risk of getting carjacked and murdered is higher (or perceived to be higher) than the risk of getting in a deadly car crash when running a red light.
