As far as "harsh punishment" for DUI drivers, not in my county. I know of a case where an intoxicated illegal alien struck the rear of a pick up truck pinning a man between both vehicles. The man lost both legs and this happened on Christmas Eve. The drunk then spit in the face of one of the police officers. He plead guilty to OWI causing serious bodily injury and Battery by Bodily fluids. He received a whopping sentence of 3 years for both. He got 18 months for each charge. Big woop. They are going to try and deport him.

Also, I am no so concerned about the drunk bike riders hurting someone else, but causing a crash where they get hurt after falling in front of a car or some such thing. I, as a police officer, fail to to something and let the drunk go home, I am negligent and can be held civilly liable. I will also admit I have never made DUI arrest for someone on a bike.
