My fail safe process to deal with police.
1) get a licence
2) get rego
3) ride in legal area like a state forest
4) understand that even then you can get done on a technicality like blinkers or from riding on single track.
5) cooperate with police, you may need them on your side one day
6) speak to police in a manor befitting point 4 and 5
This has worked in multiple occasions, one time the copper actually pointed out some sweet single to us on his map!
