Yeah absolutely. I never said anything to the contrary. There are reasons to reduce EV weight, but range ain't one of them.

Weight isn't as big a concern with EVs because they require more energy to accelerate, but they get more energy back when regeneratively braking. The biggest impact on EV range is aerodynamic, by a long shot. The F-150 lightning, for example, has the same efficiency with the standard and extended range batteries, even though the extended range battery is 500 lbs heavier.

The heat is from compression, not friction. And besides that, this thing is only flying at mach 1.5, there are TONS of aircraft that fly at those speeds (and much faster) with windshields.

The reason it doesn't have a front windshield is because the change in shape of the aircraft at the windshield, to be more vertical, was disrupting their method of reducing the sonic boom. The aircraft needs the shape it has, so a windshield would have to be like 20 feet long to offer any forward visibility.
