“Cheap ones at that.”
Trust me. Light materials does not mean cheap (as in inexpensive.) Typically, if they match or even come close in capability to the heavier material they cost many times as much.
Plastic windshields? Cheap crap at high prices.
Back in 1984 I worked for a company that made high end kayaks. The Kevlar boat was twice the price of the fiberglass model. They took the same amount of time to lay up in the exact same mold. The Kevlar was lighter and stronger. The Kevlar boat sold to people who were world class competitors.
There is a reason why a Bell helicopter costs $2 million. Kevlar is very expensive.
All part of the grand plan to make more people rely on public transit and make it necessary to relocate to urban centers.
And your average parking lot bump becomes horrendously priced.
