Could someone who has played through Sonic Riders help me ..

I travel a lot and haven't had a chance to play it. I've tried to
figure out the storyline from assorted FAQs and guides, but a lot of
stuff doesn't make much sense to me. Maybe someone's who's played
through the game can explain some things better:

1) Why are Sonic, Knuckles, and Tails looking for a Chaos Emerald at
the start of the game? Is this just what they do on Saturday nights or
something? Wander the city at random looking for Chaos Emeralds?

2) Do the Babylon Rogues take the Chaos Emerald at the start of the
game with intent of using it as an entrance fee for Robotnic's race? Or
was it just some random theft and the entrance fee for the race was a
happy coincidence?

3) So, everybody has their own Chaos Emeralds that they happily turn
over to Robotnic for the race? Nobody questions the wisdom of handing
over the emeralds to him?

4) How exactly do the Emeralds--or the race for that matter--tie into
raising the Babylon Gardens? Was that Robotnic's plan?

I appreciate your help.

It's a Sonic the Hedgehog game.

Meaning logic doesn't necessarily go hand in hand with the story.
