Ahh, yes thank you. I checked in a bit deeper then I usually do.
Packet loss, okay, probably hard to fix and requires some deeper diving.
But the ping issues, yes that's a real problem. Maybe it's not the reason for teleporting (even though people with higher ping tend to usually lose more packets and teleport), but it still screws up shooting, pitting their cars and probably more things that I can't think of right now.
