[Implemented] Unloading TAXI passengers

[SO•Yukine]

Simple suggestion. Getting a wider radius to unload passengers.

When "unloading" a passenger you always need to find a precise spot, which is not great without a visual indication (the distance, plus insim's delay, is not amazing to park at a precise spot).

Having a wider radius would permit us to correctly and safely park the car on the side of the road instead of going forward and back to find the precise spot and in some case avoid unnecessary u-turns (which happens quite a lot small roads).

Gameplay wise, it would feel more realistic to let off a passenger close to where they want (they may have legs to travel few meters) than having to exit the car and mesure precisely where they want to step off with a ruler.
