My thoughts:
I like the first design. It shatters but it at least deflects the wheel from the cockpit. It also has an opening that the driver can get out of quickly. It reminds me a bit of the windshields used on 1960s F1 cars like the Lotus 49. Only far better.
I'm also finding it hilarious that people are saying "this isn't needed", "this is the death of open-cockpit racing", blah blah blah. Well guess what. People were probably saying the same thing decades ago when they introduced seatbelts. Or closed helmets. Or chicanes. All of which were introduced for protecting drivers (but, as always, the FIA always introduces the safety feature after someone dies, not before). It's already happened in F2. It almost happened to Massa. It happened to Senna years ago. So I'm quite surprised that they have taken this long to implement it, even. (the high windscreen, not the closed cockpit, I already know that the closed cockpit is a stupid idea for when the car rolls.)
