I came to a extremely bad problem today. My engine became broken due to my excessively large lag. Meaning the engine eventually broke. But, Their was no god dam Mechanics online *Shakes fists*. So there I was, stuck in the middle of nowhere with a broken car, and a car in slot 2 I couldnt spawn. I wasnt allowed to relog either -,-. To overcome this problem, I propose you allow Multiple car spawning. It is rather annoying not having a mechanic online, a Broken car, and a very healthy car in slot 2.
This would not only solve this problem, it would increase RP Business or w/e. People could buy 3 cars and start a "Rent" Business. They could also borrow their car to other people, which is very life-like. This would also Increase the need for people to use Traffic lights. Its pretty obvious when I say, More cars = More Traffic, More Traffic = More RP.
Tis GOOD Overall :). Please consider my Suggestion.
