Autocross is the most fun you can have at 50mph or less.Lowest form?? 🤣 apparently you've never done a proper autocross. In an average autocross run you have 40 or more braking and turning events in a run of 60-90 seconds. On a track you have 10-20 in 2-3 minutes per lap. Just because the average speed is lower, doesn't make it less. Autocross will teach you car control far better than anything else.
*I do both Autocross and Track driving.
Yeah, I learned a helluva lot more about actually handling my car at autocross and the performance driving school our autocross does that I have anywhere else.
