Yes, nice comparison. First of all, the US legal system or systems you are referring to are not the be all and end all for legal systems. Believe it or not, there is civilized world outside the US that has their own legal standards and in many cases for at least as long in the US. So stop being pedantic and US-centric for a minute.
You are correct that most countries will have a strict liability for DUI's. However can one really compare this to strict liability cases where someone can inadvertently and unknowingly ingest a banned substance? Can one really get drunk any other way than knowingly drinking alcohol? Is there any banned substance under normal law that has a strict liability when one can ingest the substance unknowingly. Besides with a DUI it is not the alcohol per say that is the problem, it is the fact that you are driving a vehicle while drunk. So in that case it doesn't really matter how it got into your system but that it is in your system and you still chose to drive a car, Whole different ball game therefore.
