Middle East
- Skip Dubai, it's overrated. An artificial place born out of the sand dunes....

Instead...
Europe
- Go visit Slovenia...
- Germany, careful there. Autobahn doesn't really mean no speed limit. There are plenty of sections with limit, especially those going in and out of cities. Rather, you should go for a few laps in Nurburgring.
- France? Don't miss Mont St Michel.

Rental cars in Germany allows it... because on Tourisfarthen days, the ring is considered public roads (with tolls - the entry lap ticket). Only thing is, you will need to buy additional track insurance, in case you damage barriers and run-off areas. Worth it man, once in a lifetime experience...
