F1 has been around for awhile true. However I've never seen a full heat of them run by guys that could actually drive them. IT was exciting to watch them come within inches of each other. IT had the look to it especially those with the led kits for the rear lamp.
All it would take is a simply inexpensive kit to get going. Hop ups aren't an issue as long as the cars end up the same in the end. SC racing has many options including factory team kits and in the end they're all good. Yes some better but all get around the track.
On road has NO entry level class that is on the same level as SC racing. This is the issue. Whether F1 is it or some other class this is on roads main issue of lack of growth.
