If your car broke down around there at some 'ungodly' hour, i doubt you would be safe.
A few months back a friend of mine was approaching The roundabout at St Paul's with an Avensis from Nyerere Road and was met by 3 guys on the road and one threw a stone partly smashing her windscreen. As she slowed down, one of the guys jumped in front of the car hoping she would stop. She drove on barely missing the thug.
This was 5am... there were no other cars around.
When she reported to Central Police, one of the cops asked her "Unajuaje walikua wakora?"
She obviously replied with an insult.
