`Electric Cars` policy does not work as expected with ParkingAI enabled

Describe the problem

It looks like ParkingAI does not ensure that spawned parked residents vehicle in the district with mentioned policy are only electric cars. I’ve checked the code and found other weird issues but still nothing which could explain that behavior.

Steps to reproduce

1. Clear parked vehicles and preferably all passenger cars to despawn residents returning home in their “non-environment friendly” vehicles,
2. Paint district and set Electric Cars policy
3. From description and the game implementation, if citizen is at home and decided to spawn car it should be electric (final probability = random.Int(100) < 100 (forced probability when spawning vehicle at building located in the district with mentioned policy))

Notes

Maybe we should also try to force already spawned vehicles (and assigned to resident) to be electric, potential solutions:

• reset assigned vehicle so it may decide again if want to use car,
• swap it with electric when cim wants to use it

• in the meantime while debugging Parking 😕

Unrelated issue: reading the ParkingAI logs I noticed that TM:PE is trying to search parking spot when citizen exit its vehicle at outside connection (going outside), same for incoming citizens (just before they spawn at outside connection). Since usually there are no buildings then not a big deal but on the other hand, time is wasted for things that always fail…

Side note, maybe I don’t have enough car asset but I feel like once I created a small district in the corner with Electric Cars policy, 80% cars driving in the city are…electric. What is going on😂 ParkingAI logic for spawning vehicle when cim is at home seem to be a bit broken (or too restrictive) because when I disable ParkingAI there are loads of cars around high capacity residential buildings unlike near empty roadside parking lanes with ParkingAI enabled
