Mattel’s Hot Wheels Radar Gun might just be the coolest toy we’ve seen all year–it’s an actual, fully functional radar gun. Speeds are displayed in 1:64 (Hot Wheels) scale or 1:1 (full) scale and in either miles or kilometers per hour. Drawbacks? Range is limited to 40 feet, and the gun reads to only 100 mph in 1:1 mode. At $35, though, who can complain?
