- pak 16y agoThen one day, you kneel down to check your engine oil, and bam, there go all your credit cards. There are downsides. I'd prefer if they just made the loops a little more sensitive. A 200 lb piece of metal would seem to suffice for a true positive...
- kijinbear 16y agoSeriously, anything except a pedestrian should trigger the sensors. Car, motorcycle, bicycle, wheelchair, or a freight train from your subconscious trying to crush everything in its path... whatever it is, if it's sitting in front of an intersection and it's not on the sidewalk, chances are it's waiting for the green light! Sure, you might get a false positive from time to time, but whatever causes the false positive probably shouldn't be in the car lane in the first place.
