This is somewhat wrong...
Asstists are not mandatory in sim or arcade it is up to the devs.
Traction control is the same in both. It just limits your total % of throttle application to minimise wheel spin.
Drifting is only faster if the game developer wants it to be. In sims its slower because its slower in real motorsport.
Setup again is completely up to the developer not that it is an arcade/sim game. And the amount of detail in the setup can vary.
You can trail break in to a drift in a sim.
Slip angle is in sims aswell, especially older cars.
