1. There are a few choices. A popular one is travelling through light green transparent plastic tubes, which (seemingly with the help of some sort of vaccuum) suck you from one place to another. The tubes go everywhere around New New York - you just tell it where you want to go (it works on audio command) and it will pull you through the tubes to wherever that is. Very busy at peak hour, and impossible to use if there is any sort of blockage (as there is only one "lane" ). You can also buy a hovercar, which is much like a normal car except it flies. Obviously, hovercar-ing can take place in 3 dimensions, but there seem to be strict traffic rules so you really can only move in particular directions/roads. You can get jetpacks, although they don't seem to be popular, or you can use a spaceship like the PE crew do - just following the hovercar rules is all that's required. You can also make your own intergalactic vehicles (see "The Route of all Evil" ) although that's also not popular. You can walk, or get hovercar taxis, and hovering restaurants are also drivable (see "Amazon Women In The Mood" ).
2. There are quite a few different opinions. You can read some in this thread
. There are suicide booths, but they're only ways of making society more efficient (sorry if that seemed crude and awful). There are lots of changes:
a) You get assigned the job that best suits your ability, and have to stick with it;
b) It's impossible to get anything filed/retrieved at Central Bureaucracy (it's bad today, but it takes several decades in the year 3000)
c) Our time is referred to as "The Stupid Ages". Perhaps then, society is smarter.
d) Intergalactic travel is commonplace, so you can really expand your horizons.
e) Inflation has been kept in check - prices are similar to today's, so the economy is doing well;
f) Planets keep getting invaded;
g) People are nicer about inter-racial stuff, even inter-species stuff;
h) Entertainment is varied and advanced (you can do "Choose your own adventure" in movies, play virtual virtual skeeball, ride a dinosaur, blow up a planet...)
i) we've got heaps more sports at the olympics (including Limbo)
j) Ads are everywhere, including in your dreams.
I'll let you decide which of these are good and which are bad. But read the above thread, it's a good background
