Nobody flashes their headlights with the intent that someone will speed up. Driving at night, you're not even able to determine whether oncoming traffic is speeding.

It is literally telling someone to obey the law, because the law is watching.

Maybe they’s why people post on the app too, to remind folks to have their documentation in order.

If you have the app, you likely don't need the reminder. You're either evading ICE or helping other people steer clear of ICE.

Police notifications on GPS don't really give you much notification to turn off onto a different road or to avoid them, at least on freeways, which is the only time I've seen them.
