"If they were really concerned about impaired drivers and highway accidents, injuries, and deaths, they'd be advocating stringent tests on reaction time (to get a license) and vision (to get a license)."
I support that fully. Blue hairs NEED tested! OH and I require Valid proof of ID too on that note ;)
"They'd also be vigorously lobbying for laws about cell phone usage"
Some places have seen those laws already, more need them. I support them too.
"might impair"
Are you saying that acohol is not proven to impair? Interesting useof the word "might".
"They'd be advocating that people with medical conditions that might interfere with their ability to drive should not get licenses. "
I do.
I still do not advocate prohibition of alcohol.
