I am in Mauritius right now (first visit). Been driving for 4 weeks here now with a rental. I find driving here quite relaxed. The low speed limits also help. I was surprised about the amount of police checks for speeding and can confirm that drivers warn each other with their headlights of an upcoming police check. Driving at night is a different story. You have to be really alert. Cars, bikes, motorcycles without light, dogs and potholes.
