We all know from Robotics to TV and to Rice cookers are all basically Japanese brands. The top-of-the-line electronics are Made in Japan.
Why Japanese don't give a thought on making a good radar detector and Laser Jammer? I mean Japan even have nicest mod. cars for drifting and racing. Do those people don't care about the cops?
If Japanese being serious on radar detector business, I am sure the V1 and Escort will be crying out loud.
