There may be regulatory implications in some areas. Even though the studs are retracted, they could be illegal in areas that prohibit studded tires.

Pretty impressive idea. If it works as advertised, the retractable studs could be a great compromise between dry pavement comfort and real winter grip. Curious to see how they perform in real-world testing.
