surely it's just evolution.

Pro-street was all the rage in the 80's / 90's. Why there were very few if any road race, circuit track style events for street driven cars. It was basically only drag style events.

Also emissions laws and registration laws meant there were few if any limits, so driving a back halved, massively blown car on the street was doable.

No longer.

Now restrictions limit that style of car.

Also there is way way more circuit track style events.

I hate the name pro-touring. To me it's evolution, and the thought leaders / pioneers will always be creating evolution long before it becomes main stream for us mere mortals.
