OK, are the computer cars faster? And other questions.

1. I've suspected that the computer controlled cars are a little faster. They always seem to recover and get back up to speed much faster (e.g. if we both get his with a cake) Is that true, or is it just that they have perfect reaction times? Do all of the cars have the same acceleration?
2. I was in a Grand Prix, and I started out at the front of the pack. I had a good start. And then zoooooom a computer cars goes right by me. There was no nitro, presents, or zippers. Is there the concept of "drafting"? I can't think of another way he could have zoomed past me. Unless maybe he got bumped from behind?
3. What determines how long you have the parachute? Sometimes it's very short, sometimes I seem to have it forever.
4. I'm on the latest SVN version. I see some source files that are updated that are related to addons. Is this "hidden" functionality that is being worked on that can be "unlocked" or is is just under development. I don't see the addon manager anywhere in the app, but I know it's on the roadmap to be worked on.
