I have only ever driven in England, so I have no experience of driving on the right hand side of the road.

You might try experiencing the delights of Sidmouth folk week - the first week in August, though I think it is spread out over nine days now - and when it finishes on the Friday you can go straight to another festival for the weekend, then you'd probably feel like lying down in a darkened room for a few days to recover. You should be able to use the festival busses and public transport, maybe even get a lift in between festivals.

As for driverless cars - I think that they are just about legal, but practical is another thing altogether.
