I thought it would be good to add this mode to the cars, because many times it happend to see cars taken by the IMPOUNDERS, just because there is someone to push it in the middle of the road.
This could be a safety method for those who park properly on the street, not to surprise that their car is taken up, although they knew they parked it properly.
So once the handbrake is activated, the car can no longer be pushed or at least can be pushed, but harder than when the handbrake is not pulled. (and besides, there is also a simulation of reality, because the cars have a handbrake).
There are a lot of mods on the internet related to this handbrake system, so it's very easy to find.
I played on a roleplay server and this handbrake system was NOT on the spacebar button, so it can be added to another button, in order not to spoil the drifts we make with the space button!
