How accurate are those automated roadside emissions checkpoints?
Is anyone running without primary or secondary cats concerned about those things?
I passed through one of those the other day. I'll see soon enough if my mod is detectable by that.
These are set up on the on-ramp to the highway, so by the time you see it its too late. There's a van on the shoulder with what looks like an infrared type of camera on one side and a camera to get your license plate.
