Hello, were you get your windshieldParts support is pretty abysmal, even under warranty with connections to Polaris. It's not just Slingshots, it's pretty much anything Polaris makes.
The background is many of the parts are made in China and trapped offshore due to the currant U.S. government policies, making the previously "not great" parts support become "far worse." Most vehicle manufacturers are facing similar supply problems, so realize everyone is in a somewhat similar situation. Maybe get a used scooter on the cheap? The Honda PCX150 is really good.
Glad you're okay, that's a pretty harrowing situation. The good thing is the Slingshot has a very crash-safe frame for the type of vehicle it is, somewhere between a car and a motorcycle.
