Some pros and cons I could come up with:
+ Could spice things up
+ Catching a runaway becomes easier
+ 1:10 lap times
- "no contact" rule not clear anymore
- rules not in level with major racing leagues
- defenitely more incidents to resolve
- mutual consent needed or can you just push whenever / wherever you want
- favors team drivers, and puts solo drivers to underdog position even before the race starts
- more arcade feel
I voted no, because I can't see it to fit in our servers. I'm however open to test period to see how does it feel like in practice.
