From one perspective, I understand your argument, and it is the obvious argument. So I get where you are coming from. But think about it like this: the government is just trying to save lives, right? How is the life of an "innocent" driver who is hit by a drunk driver actually any different than the life of someone who dies from heart disease or Diabetes? You can't say - objectively - that there is a difference. Maybe the "innocent" driver on the road was actually a criminal, while the person who died from Diabetes was an upstanding citizen, who contributed positively to the community; this person - one might argue - was a victim of poor parenting that resulted in addiction to salt and sugar at a young age, and a lifetime of poor eating habits (just a hypothetical for the sake of argument). Are the lives of 10,000 people who die per year on the road as a consequence of drunk driving really more significant than the lives of the 900,000 Americans who die every year from Heart Disease, Diabetes, etc.? One could easily argue that the impact to society of the "obesity crisis" is far more significant than the impact of 10,000 tragic deaths. What is the increased cost of health insurance as a consequence of the obesity crisis? How do you measure the pain and suffering associated with Diabetes? It is a horrible disease. I'm also not suggesting that we do nothing about drunk driving. On the contrary, I'd like to see more enforcement and more significant penalties. A single infraction, and you get a breathalyzer installed in your vehicle, or something like that. There are ways to address the problem without imposing a blanket solution on all drivers - regardless of their driving record. Lastly, this kind of legislation will shift what is considered an "acceptable" level of government monitoring, and that is a slippery slope.
Anyway... thanks for the conversation. I won't comment on this anymore as this is a car-enthusiasts forum. If you want to continue discussing this, we should probably do it using the private conversation feature. All the best.
