When I was chasing, I found that every time passed other police cars, they would not automatically join the chase. How can I make the passing police cars automatically join the chase?

 

thank you~

The AI is not geared for that automatically. You have to make a request with the B-key-menu (default-key B)
In that menu you find different backup-options and the one you use for chases is code-3

It wont necessary be a car you just passed, in fact the game insert an other police-car and he will back-you up, or drive you off the road... Depends on ...idk..
You also need the back-up menu B to call ambulance, firebrigade and transport of kneeling apprehended crooks.
Do also investigate your M-menu. Lot of the gameplay depends on menu options

 

Understood, can a certain type of vehicle be designated for transporting criminals?

I believe that any of the cars you have entered as police-cars will be used for transport. All of the default police-cars at least will.
You can call a specific branch of the police in the B-menu, and they will use their car, but i doubt you can control it better than that.

我相信您作為警車進入的任何汽車都將用於運輸。所有默認的警車至少都會。
你可以在 B 菜單中呼叫特定的警察部門，他們會使用他們的車，但我懷疑你能否更好地控制它。

I found the file to change the car, thanks for your help
