Yeah! Sounds like a great idea and, as you say, one that at first glance
would seem reasonably easy to implement.  What info about your driving
would the computer require?

As far as I can see the most important parts are the driving line, when
you start braking, how much you tend to lock up under braking and
relative speed through the corners.  Then all that needs to be done is
get a mean average for these 4 elements, add a little variation to the
AI drivers so that some might be slightly better whilst others are
slightly worse and you've got some pretty similar driving styles out
there.

Whether this info could be updated whilst actually racing against other
cars I'm not too sure, what with frame rates being at a premium as they
are in GPL, but it sure would make a nice feature:-)

Spot on, Byron :o). This might not be the case for all racing sims,
but it's probably spot on regarding GPL.

cause noone has understood it the first time they've read it yet :o)).

It would be nice to drive against yourself as you were a couple of month
ago, to see where you have improved. It's always nice to see oneself improve
:o).

I would love to race against other drivers AI :o).

>>should make for some really close racing, and you will think the AI

>>While you race yourself, you will of course improve, and the "record
>>driver" feature could be on during these races, so you can later
>>choose to race the better version of yourself.

>>You could also save your AI data, so another driver could race against
>>your AI, or race against a lot of other drivers AI at the same time.

>>It would probably be great practice to prepare you for online racing.

>>Watch a race at Mexico (GPL) from one of the fastest guys on the net
>>and then watch the AI in GPL. You realize the AI have no clue on which
>>racing line is the fastest :o). The AI in GPL doesn't drive like Jim
>>Clark did either, but the fastest drivers on the net do :o).
