14 coolest toys for the holiday season

Hot Wheels now makes AI-enabled smart cars.

Mattel's AI race system ($100) features two cars fitted with smart sensors. As a car rounds the 20-piece track, it reads coded patterns embedded onto the bottom each piece, thanks AI technology baked into the controller.

The controller -- the system comes with two -- syncs up with the track. It then monitors how many laps each car has completed and helps it stay the course.

The track itself can be arranged in 40 different racing layouts.
