Since I approved it, and since no one else seems to want to look at it, I can give you my opinion. . .
I liked it, it seems like it would become very useful for people with cars/other vehicles in their maps. There were no bugs that I could find, but then again I didn't look to hard for them. An original concept that I don't think has been done before, not many triggers (and not complex either), so it's fairly easy to implement. Very well done.
