Layout arrangement in the jamaica.

[Yasen]

Hi mate!

It's a good suggestion for me overall considering the insane driving by most of the civs and (suspects trying to loose the cop behind). They are crossing this intersection like kamikazes no matter the traffic light.
There are added already object with speed bumps that do the job done very well.
In one hand,
When a serious accident happen there and multiple cars are involved the chance of compensation is close to zero. But as a option we have !report.
In other hand,
The intersection seems pretty realistic compared with real life. Ive watched a lot of police chases in US videos in youtube. They have very similar cross roads like this just after the highway. Arranged with traffic lights only.

In general the layout its good enough. We have danger zones with heavy traffic on all maps similar like this.
The cop behavior reaching this zones/crossed roads with no visibility and when there is a traffic should be: lights, fast siren, bull horn, checking the map if you have that time/chance, reducing the speed even if that will cost you loosing the suspect if the chase becomes more dangerous for all.
4.1. Proper behaviour
Cops are expected to behave and act like cops.
That include the care for others drivers and avoiding incidents as much as possible.
Even cops in pursuit should slow down for stops, give way signs and traffic lights when there is a danger for civilians.
Chasing the suspect and trying to catch them on all cost can end with reports and revorked license.

Thats are just my thoughts. I hope they are helpful.
