Yeah, I live at the north end of the island. The tax is currently 10% basic, 18% above with a £8500 earnt before being taxable.
There are speed limits, though only in towns, though they're rarely enforced - I've been driving for 4 years and I've seen one police radar guy.
The airport is very quiet though, heh.
However, yeah, everything is more expensive, there is barely any nightlife, there is 3 cinema screens, one bowling alley (I'm not making this up :P), and the locals don't generally have a brain cell to share between them.
