I am very concerned that there is still no objective and quantifiable value or measurement tool to allow law enforcement to apply impaired driving charges accurately and constitutionally.

I guarantee you we will see the number of unconstitutional roadside detentions and search & seizures sky rocket.  Car suddenly smells like weed, drug sniffing dog mysteriously "hits" on your car.  All of which tends to happen after you assert our rights. 

Know the law, know your rights, know how to conduct yourself when your rights get arbitrarily stripped.  Above all, record all interactions with police.  All the time.

Everyone is accountable.
