I'd say we definitely need this ngl, but it would be better if it gets added as a setting and the player can choose himself if he wants wanted criminals to ride his vehicle.
Using /disturbance won't be as fast as just getting into the car. Just like GTA V as long as you agreed that the wanted player enters the car, then you accept being wanted too. The issue here, the players will be using this to troll the innocent people across the streets and spread the wanted level, but I see that this can be prevented by locking the vehicle nor removing the player from the CITBook. Positive.
How is a wanted player entering a vehicle driven by an unwanted player currently handled?
We get this massage ''Wanted players are not allowed to be driven around by an unwanted player!'', then get ejected immediately.
you simply can use /disturbance to get some wanted points , no need for this feature , negative
