http://www.lfsforum.net/showthread.php?t=69754 - LsC Cruise application. License - requires credits for the creator to be left.
http://www.lfsforum.net/showthread.php?t=67128 - A project that I had started, but never finished, which led to it's release. License - no credits or anything required for personal use.
Some time later I will maybe release OsC's source. The police system on it was(IS*) very sophisticated. But then I started doing major re-arrangements, and stopped in the middle of that process. Or in other words - it is currently not working. Some code cleanup is also on the list of things to do before releasing, because it is very messy. And maybe some documentation, if I even remember how things work myself.
No promises tho, because I've got much stuff on my head right now.
Also, PRISM's cruise addon is in refactoring stages.

So please, check the thread titles at least on the last page, before posting a thread, that is identical to a one, posted a few days ago. That's just a request of course.
