From the article (see related link):
"A new form of intimidation, victimising mainly female drivers, seems to be sweeping the streets of Johannesburg, according to Guard force Int'l Transportation Ltd."
The article goes on to describe two separate incidents where occupants of a taxi intimidated woman drivers for no apparent reason.
While I'm usually first to complain about crime in SA, something about the article doesn't make sense. It's sensationalised, with the intention of scaring people as opposed to informing them.
Health24.com should know better.
