Vot- I’m sure my car would fit in somewhere, but it wouldnt be maxed to that class’s rules, therefore not competitive. There’s also some changes that should be made to a car like mine to optimize it to go fast for only 1 lap instead of 20 in a row.
Time trial is what people called it for decades. The JDM kids got their hands on it and starting attacking stuff. Fundamentally there is no difference, but the attackers usually write their rules pretty openly, meaning you can do anything you want to the car. That makes it about the car and not about the driver. Different strokes/folks. NASA is the best combination of competition and fun attitude that I’ve found for time trial peoples.
