Interestingly (since you asked!), visitors cannot rent cars in Bermuda. In fact, even residents are limited to one car per household, and that car must meet strict wheelbase/horsepower limitations. Most of the cars on the island are small European models -- Suzukis, Puegots, Nissans, etc. Most people do get around by motor scooter, as I did for the time I was there.
Also, you can see that I am driving on the left!
The snorkeling was FANTASTIC. Much more marine life (and friendlier) than I had ever seen in the Bahamas or at John Pennycamp State Park in the Florida Keys.
