I wonder if there would be enough people willing to "learn" from and with each other ... like driving some 100 laps around one track in order to learn to give everyone enough space.
I did race with my brother in GT3 and we gave each other enough room - of course, it comes to give away precious tenths, but it's really way more satisfying if you have close racing and no "dirty" bouncing-off-the-enemy all the time.
If some people got to know each other well enough, it would be cool to let everyone choose cars so that there's a leveled field which gives everyone a chance to win.
It would take some time, maybe some months, but if it would come to choose more and more cars, different cars and still having good racing - that would be too good.
If so, i would take the following cars to the track:
- the Mazda Cosmo Sports '67
- my Lister Storm V12
- and a red Honda S500.
