This Hyundai Wheel Has A Built-In Snow Chain That Pops Out

Hyundai has come up with a solution to get rid of traditional snow chains. It's called a shape memory alloy snow chain and it replicates the functionality of traditional snow chains at the touch of a button. How does it work? The newly developed wheel and tire assembly has built-in radial grooves at regular intervals. There are shape memory alloys inserted into these channels, making the assembly look like a pizza.
