I ran into a very strange bug in Georgiana over a specific parcel (location withheld) where no matter what height I flew over it in a vehicle I would be forcibly unseated from the vehicle. I'm talking any height, even beyond 768 meters. Also there were no other scripted objects within 96 meters of me.
It was probably yet another sim bug that amplifies the effect of one of those silly "security" scripts. I had an incident a few weeks ago where a script in an adjacent sim was harassing me on my land, so having a script harass me without regard to height limit didn't seem impossible, but its definitely a bug in SL. So I filed a report. Here it is:
>I keep getting mysteriously stood up from vehicles in Georgiana, this
>time at <XXX, YYY, 846.36963> which is well beyond the 768
>meter build limit.
Short and to the point right? Well that's what I thought. Here's the reply I got today from Namewithheld Linden:

So apparently my vehicle scripts need llSetVehicleFlags(VEHICLE_FLY_REALLY_HIGH|VEHICLE_PILOT_ASS_GLUED_TO_SEAT).

Seriously though, there's no difference in sitting in a flying vehicle at 100 meters or 1000 meters unless you're using an llSetPos based motion which is limited to 512 meters Z axis. But even then, the only way you get unseated from a vehicle is by flying above 4096 meters and that's because all objects cease to exist above that height. The only thing that will involuntarily unseat you from a vehicle below 4096 (that I know of) while keeping the vehicle intact is an llUnSit by a script that acts on your avatar when you are over land owned by the script's owner.

My point is this: How is Linden Lab supposed to debug Second Life if the debuggers don't know how Second Life works? I bring this up because this isn't the first time this has happened and in about July I finally just got so fed up I quit participating in the whole bug reporting thing. I think I may just go back to that after this because filing that report was pretty pointless as you can see. Several other bug reports filed around the same time as this one have either just been ignored or answered with the same kind of unhelpfulness. In July I got told some bugs weren't bugs, then oh, whoops, they are bugs after all!

Incidentally the problem in Georgiana is stopped. I IMed the parcel owner and asked him/her to turn down the range on his/her script and after that the problem stopped. It's a good thing too cause Georgiana's sky was getting littered.
