Lexan Windshield Question

Just a clarification on the usage of words and material characteristics:

"Lexan" is the trademark name for material polycarbonate.
- Polycarbonate is flexible and nearly unbreakable allowing the use of thinner and lighter sheets, but its more susceptable to scratching than plexiglass.

"Acrylic" is the non-trademark name for the material plexiglass.
- Plexiglass is harder and less likely to scratch, but also more likely to break like glass if pressure is applied.

The "clip and strap" rule application is just stupid now. No better way of saying it. For instance, you can run a spec miata in SM and ITA without clips, but lord help you if you decide to run FP with the same car. Now you must have clips and straps. What changed with the car? Now if you change to a Polycarbonate windscreen and abandon the factory installation method, that would be a different matter.

There are many of those inconsistencies, a car that can run in IT and Prod or GT, go essentially the same speed and must have a huge disparity in safety prep.
 
Or the IT cars that are allowed to run in STU, but IT requires a handheld extinguisher while STU requires a full system. uhhh wut?
 
Thoughti saw in GCR whenI started racing and read it all that in Production you had to remove all glass. Has that changed or is my memory bad?
 
What we're pointing out is the identical car in ITn/nP/STn has different safety requirements.

The safety rules are not consistent.
