Well my suggestion is basically just making it more reallistic to actually turn a vehicle's engine on by adding something like a " toolkit " to the store and in order for someone to actually turn a car's engine on that's not his he has to type something like /hotwire and then he gets a scheme to complete or just waits like 60 seconds, you can even make it so that he can fail or succeed depending on luck. The reason why I'm suggesting this is because it's totally unreallistic how someone can just turn a car's engine on in a matter of like 2 seconds without having the keys, even if he was the biggest genius expert car jacking legend in the world he can't simply do that in a matter of 2 seconds, plus I think it would be more fun and more legit and it would make car jackers have to put way more effort into jacking a car including looking around them as there's time to wait, etc etc etc...
P.S : I understand this is a light RP server, however this is by no means close to a " heavy rp server " type of thing, however, a minimal level of realism should be there, especially when it comes to this thing, in my opinion.
