The Spyder is made by BRP, Bombardier Recreation products is what that stands for I think. Bombardier is famous for inventing the snowmobile, and BRP makes the SkiDoo brand. The original Bombardier company split into several divisions making aircraft, train cars, boats/skidoos/spyders, etc.
The Spyder is essentially a wheeled snowmobile. The target market for them is snowmobile owners, who now have a similar handling machine to ride in the summer. Plus they are road legal... most places you can use a snowmobile on roads only in quite limited circumstances.
I've ridden (driven?) a Spyder and it really moves but handles totally weird if you just came off a bike. Basically just like a snowmobile - you can lean your body into corners to avoid tipover but it steers like a car with handlebars. It solves the sidecar/trike problem of hitting stuff because the widest part of it is up front where you see it as you approach a tight spot. I've seen several sidecar crashes where the hack crashed into a sign pole or building.
