Flossie, which area to do you live in? (Note to self, watch out driving on a Friday in this area

)
Same, yet opposite experience for me when I lived in Barbados. It took me a couple of weeks before I felt comfy driving on the opposite side. As mentioned it was easier to adapt when traffic moved slow.
Mardigras, don't panic when driving. At most people will honk at you, but everyone makes mistakes everyday driving. As for taxis, they can take you everywhere.
