I've never had a problem with jerkiness of cars even at 4pps, had wheel to wheel racing without any issues.. now if the net code was as bad as you say, that wouldn't be possible.
I find that you have a much more enjoyable race if you don't go aggressive on every corner, if you treat other racers with respect you get the same back.
Only problem with yielding when you're 2 abreast is when you both yield: A night or so ago on so1 into the chicane me and a friend both yielded, managed to squeeze through side by side somehow
On my server pps is set to 4, it's at that value because a while ago Scawen stated that 6 was only intended for LAN servers. Is this still the case or can it be increased to 6 on a WAN server with no detrimental effects?
Just having a browse through the server list an see a few servers running with 23 slots, I thought the maximum you could hold was 20 players at once, is 23 correct?
