Again, we are in agreement that riding horses, driving ox-carts, handling firearms or even wielding a butter knife when too impaired to safely do so is reckless, but again, how, exactly, is this different from being completely sober and riding one's horse into a crowd at a full gallop?

I submit that unless you can elucidate some substantive difference between these sorts of recklessness, there should be no special, additional punishment for simply riding a horse, or driving a vehicle, in a safe manner whilst having a BAC over the arbitrary legal limit.

Punishing people for the harm they *might* cause, even if it does not come to pass, is an invitation to tyranny and has no place in a truly free society.
