My IC is comming tomorrow afternoon, after time for Kouryou runs out, so you have a chance to enjoy some racing. We will cut the road into three stages:
Safehouse to the point where you will have to decide if you will choose
SE Auburn Black Diamond Road or
Auburn Echo Lake Cutoff RoadBoth ways are possible, the first may be higher thresshold but lower surveillance, the second is a highway with high surveillance, well it would be quite easy to drive, but speeding may catch attention of preying eyes.
To this point, encounters are possible but not necessary.
Driving thresshold: Easy (1) + Light (1)=2
Only places difficult will be passing
Cassey`s: Easy (1) + Restricted(2)=3,
T-crossroad where you approaches
SE Lake Holm RD (Easy (1) + Restricted(2)=3), Serpentines before you approach
SE Auburn Black Diamond RD (Average(1) + Restricted(2)=3), and the point you enter
SE Auburn Black Diamond RD (Easy (1) + Restricted(2)=3)
And then it depends on what road you decide to follow. Whole distance to this point: cca 5 km (according to Google).
It is raining, so apply "bonus" for racing tires, where appropriate

So it would be roll for every 500 meters = 10 rolls
Thressholds as Follow:
2 / 3 / 2 / 3 / 2 / 2 / 2 / 2 / 2 / 4 / 3
If you exceed the vehicle speed, add +1 to thresshold for every 50%
4xShadowing roll (Driver):

T-cross,
SE Lake Holm RD,
