'No refusal' is a recent development, essentially made of whole cloth by the police. Who are they to make that call?
I remember being stopped at the only sobriety checkpoint I and there was no way out of it.
Most states have a provision in the law that an alternate route must be provided. Naturally, the police will be happy to play cat and mouse by watching for and pursuing anyone exercising a few last scraps of freedom by using such an alternate.
In addition, most checkpoints did not stop and inspect every vehicle and they certainly had nothing to do with seatbelts (another thumb-screw law originally sold under the rubric of safety).
It was totally unoffensive.
Words fail.
