Reggie is a one size fits all solution while Sophy needs to be trained per car. Now, when we do the glitch, we are transplanting Spohy training from one car to a similar one. This is fine for our use, but PD as a company must meet other demands.
Ya, no we aren't. What you are suggesting misses one giant hole your logic, and that is, what car is it choosing from?
If the glitch were stealing a file from a Sophy supported car, then every glitch car would work like that other (mystery) car. Ergo, every car would work flawlessly. Also, it doesn't explain why Sophy cars are supported on one track, but not others. Especially, the new Power Pack cars, since they have a Sophy file.
The only answer is that it is car + track.
Use the glitch with the Unimog at Catalunya. The Unimog get's confused and drives straight through La Caxia (turn 10). Why there? Well, one possibility is that the game uses the new configuration, but the track is modelled accurately where the old configuration is still in place and there's no collision wall to stop you following the old track. Once it hits the cones though, the collision seems to make it realize that it has gone the wrong way, which is somewhat interesting to watch.
Everything else I have tested works fine.
So, it would appear, the is no "knowledge" of Catalunya for the Unimog (where to stop, where to go, where to turn). It if were stealing a file from another car, it should overshoot every corner, but it only overshoots that one.
I WISH they would just adopt a single default file, then every car would work with Sophy.
