Laser speed guns use lasers by Doppler shift measurement.
It is like paintball mixed with laser tag. Same rules as laser tag but you use paintball guns with rubber ammo.
Laser speed guns can target ONE specific vehicle, where radar may read one of several vehicle. Laser is harder to detect in advance, and harder to jam than radar.
Toys R' Us has a fine variety of laser tag guns. Try shopping online as well.
