Also, my GF's cousin has a mid-90's Saab 900 Turbo hatchback, and it has a light that says "Shift Up", in red. I couldn't find pics though, and her car's quite far away for me to go get one at 7am. :P
Umm, last i checked, inertia doesn't work that way, lol. That'd be like you saying:
"I was accellerating to 50mph, and took my foot off the gas. Because of the inertia, i went up to 63mph before i started to slow down."
No. You slow down the INSTANT power is cut off. Inertia cannot add speed, mearly preserve it. Acceleration can't have inertia.
What's happening is that the limiter kicks in at the proper speed, but it's not instant because it never cuts throttle to zero. So, if it kicks in at 48mph, and you've got a very fast car, it's possible that the fact it doesn't cut to zero throttle means the car is still slightly powered AFTER 48mph, taking you past 48mph to 49 or 50, resulting in your penalty.
It could be a clipping problem based on your speakers/computer's individual volumes, if it's not an actual LFS issue. Check your volumes and make sure they're not too high to take the additional sound volume added by the reverb/echo effect.
Here, you see many members getting kicked from the server at once, but not all. I have no confirmation whether any in particular have the Z patch, but it's happened quite often since the release of Z4, and more often since Z5's release.
I don't know what other info i'm capable of providing other than i'm not on Z4+, and i don't get booted.
