Building up on the idea of using AI to do consistently the repetitive work and free our attention to read telemetry and edit the scripts of the cars I made four more different layouts.
Right-left skid pad for distributing the wear on all tires evenly and immediate transition between the directions for measuring AI's awareness
Right-left skid pads connected with straights for measuring braking and trail braking
Straight line top speed on 8000 m distance with return leg like 1/2 Boneville straight. Cars with too weak brakes or too wide turning circles won't succeed completing the loop
Washboard-type road with incremental increase of ridges peak height starting from 15mm to 55mm with step 10mm, AI spline of A2B with straight line hard braking at the end. "aiPush" in AI app is the way to gradually change the car's speed on the straights (~50 is what balances the speed near the minimum for AI without despawn).
The initial layout of single direction skid pad is included in the update's package so overwrite it when prompted.
All layouts provide for a bit of fun too if used in race mode to organize 1-on-1 dogfights between player and AI or 2 different AI cars. Timings are posted accordingly. Starting grids put one opponent at disadvantage on purpose.
