Vehicle(s) leaving pilots/passengers behind issue in 1.9

Post 1.9 I've been having quite a bit of problems with conventional air vehicles or anything traveling faster than 20m/s suddenly departing presence with my avatar. I end up sitting, frozen in space, while the vehicle continues on it's merry way. Teleport fails, sitting on any nearby object fails. The only recourse is to relog. This isnt on sim crossings, but just in the middle of any sim, populated, or bare as Fortuna.

I've experienced this in Cubey Terra's Tigershark, Linden/Terra flightscript vehicles, vehicles based on the ZX4 helicopter, pretty much everything.

I'm mostly in SL for the aviation aspect, for the joy of building aircraft for myself and sharing them with others. It's a real shame that lately about the only thing we can do reliably is look at them sitting on the ground.

I've been having the same issues, though I've only had them when I have been traveling across sim lines. I pretty much don't dare "fly" anywhere anymore and just tp or fly regularly, or fly only in sims that are not connected to others. This is a MAJOR issue.

Yes, i must concur that this is happening to me as well. also with the A3 Barracuda created by Aleksandr Martov. It literally sends me into a flat zero G spinout just like an engine flameout..but its not scripted to do that...after a bit, it just leaves me sitting in mid air, or throws me about 2-3 sims, leaving the aircraft to keep spinning off in its current heading. Had to go find it and catch it. this occurance has happened with other aircraft as well with me. I have even taken off ANY excess attachments that alter MY personal flight speed, and any other attachments that wasn't nesaccery.

This is a very old issue. What happens during a sim border crossing is that for a short period of time while one sim hands you over to the next, your client isn't receiving information about where you are. During this time, the client tries to guess based on what information it does have, and 9 times out of 10 it fails causing unpredictable behaviour and loss of passengers. There are scripting tricks to try and lessen this effect but they're not 100%. That and the state of our ancient Havoc engine has made vehicles less than satisfactory for a long while. I'd guess the problem's getting worse with SL upgrades as these seem to be slowing the game down even more for most people.
