Sometimes I have to wonder... When designing a RACING game, why make no effort at all to have the game adjudicate racing incidents? Oh yeah, I forgot... GT5 is a DRIVING game! I guess it's only coincidence that ALL the driving takes place on race tracks...
It should be part of the software to say 'If you get four wheels off the track, your engine is cut and you have to give way to on track cars before you can reestablish yourself'. It should be possible to have a 'zone' from your center pillar (or whatever the game chooses) extending sideways out from your car, and if contact is made during a corner (or even a straight), if it is made BEFORE you cross this imaginary line, you get a drive-through, if it is made after you cross the line, the front car gets the drive-through. It should be easy for software to calculate (or look at your lap stats) to determine the fastest you can make it cleanly through any specific corner. If you enter MUCH faster than that, and then make contact - drive-through and if you brake WAY early for a corner to get the trailing car to tap you, that's YOUR fault - drive-through! If you cut a chicane and gain position inside a hundred yards or so (because of the speed advantage doing that gives you), drive-through.
These all seem to be things that the software itself could calculate, and act as a 'game steward', and impose penalties. Better than leaving it to the players themselves, to be honest.
The same could be done for 'lurkers' who like to park round blind corners, or drive backwards around the track. Do either, get booted automatically (if turned on by lobby creator). I am sure that most of us could think of some way the software itself could determine the difference between a 'tap' and a blatant 'shove'.
Flags would also add one more degree of realism and immersion. So would flag girls, too, if you like! I miss them from Shift!
But, unless you simply say that GT5 is a DRIVING game (and in which case, why do it on race tracks?), some effort ought to be made to adjudicate racing RULES by the software, not the players.
There are several Special Events and License Tests where VERY strict contact and track cutting rules are rigorously enforced. Apparently, the game CAN adjudicate at least SOME infractions, and more could be added. Time to add these to Lobby Rules (as an option, for the bashers out there!).
Maybe a whole 'Pro Mode'? Full damage on, full racing rules enforced, kitty litter MUCH harder to drive out of, grass MUCH slipperier, No track cutting of ANY kind. Drive-through's for EVERYONE!
