RE: unethical way of hunting
I don't think it would be as hard you think, especially at night. In my area they just stand there and look at you in the middle of the road sometimes. I have had to actually drive around them a few times. Some deer just don't care, and the headlights seem to fascinate them.
During the day, I don't see it happening.
It is getting to sound a bit odd though isn't it.
I have met guys that hunt deer with there vehicles though. An old beater truck will thump one pretty good if you can get close enough to it.
