I agree with Go_Alesi about pitlane speeding. GP4 has integrated pitlane driving control and so much routines to be modified before we can used for manual speed limiter like EA's F1-2002 does. I've play with disabling auto speed limit during race (so you can speeding in the pitlane like as practise session does), but what a mess! Here the results:
1) Using keyboard/keypad is not possible to enter pitlane sequence precisely.
2) Pitcrew sometimes not appeared, and causing car stuck.
3) Sometimes the car just stuck after refueling.
4) And more other strange events!
My conclusion is, replacing standard auto pitstop with manual pitstop + speed limiter is
possible but we need working on lots of routines that should be patched, and this is require much of time. Bacause of this, I abandon such idea at least for this moment.
For safety car idea, no comment at this time.
For penalty when player car causing accident/collision with other car, it's already in my to-do list. I just need more of time to add it in drive-thru penalty tweak. In some next releases, it should be available.
These are some features can't be applied to drive-thru penalty tweak:
1) Implemented into AI cars.
2) Show a graphical display about drive-thru penalty status. GPxPatch has great features on GP4 graphics handler, and maybe better if you ask Rene to replace that simple black-flag image with a new good one and adjustable so can be shown at different position on the screen.
3) Change/replace auto pit speed limiter with manual pit speed limiter through pressing a button. See my reasons above.
4) Drive-thru for overtaking while yellow flag shown.
5) And lot of them which I can't remember right now.
