Just a matter or perspective. Most car toys are just a means to make the driver feel more confident, not actually improve the car. Train the driver, work on the safety and car dynamics and you will do great!

Look at all the effort that goes into monkeying with a car. Then if the driver has a fight with his girlfriend it all goes to hell. Or, if he loses it on a specific corner, just watch the times go to hell.
