Vizsla et al
The law has not changed in that regard it is one car per household though a small number of people can get around it by having Government or company vehicles but essentially its one car per house. The cars have got bigger and more numerous than when i lived there but with only 29 sq miles and no more roads than in my day your advice about scooters is best to be taken very very seriously.
It is not the place it was thats for sure -they even have crime now and gangs; nothing like Jamaica or some of the islands further south but Bermuda is so tiny you cannot 'maintain seperation'.
It is true that there are things to see -Dockyard is one and the lovely old town of St Georges, which is really pretty, at the other (airport) end of the island is another.
I do not like putting doubts in peoples minds about a place that was a happy home to me and family for ten years but it is expensive and there is more to it than gets put in the guide books-- Check out The Royal Gazette
for the local daily newspaper and see what you think.
If you to go to the Azores at elast you may get to see one Bermudian feature , the white limewashed stepped roofs of Bda are I am told not uncommon on the houses of the many Azoreans who have worked in Bermuda since they helped build the airport (Kindley Field as it was and always will be to me) and as agricultural labourers ever since.
Good luck and good wishes for the anniversary
