With radar we're looking for advanced warning so that we get everything shipshape before the LEO comes into view. With laser we've got between a vanishingly slim chance and close to no chance (depending on detector) of getting anything like that. So what's the point?
With my STi I'm pretty sure if I was shot I'd get an alert. Advanced warning? The remotest chance.
With my V1 I'd be confident if I was shot it'd let me know. Advanced warning? Maybe three or four times the remotest chance? Still next to no chance. Problem is that to acieve this level of incompetence they've wound the sensitivity up to the point that it will false alert to... my DVD/SatNav, every traffic sign that uses LED's, the brake lights of some cars, the headlights of others and the cruise control of yet more road users. And out of this stew of garbage I'm supposed to pick the once in a blue moon advanced warning of a real LEO? Isn't this the worst of all possible worlds? Next to no protection and bucketloads of falses?
So why do we persist in comparing the laser capabilities of the various detectors as though it actually translates into anything really useful on the highway when in actual fact they're all various shades of rubbish?
