This was mentioned before in another post by some one else but the point is a good one. Drivers are awash with distractions while driving. From radios, to cell phones, to passengers, to road signs and billboards, to 6 hours of sleep instead of 8, to all of the other cars on the road, to motorcycle riders passing within ones lane on the side during slow traffic conditions (legal but distracting as all hell). Are we planning on banning all of these? This summary doesn't even state how distracting the impairment is as the stated conclusion merely states that the impairment is reliably present. I'm fairly certain one having a bad day at work would generally result in a reliably diminished ability to drive.
To be perfectly honest, I think motorcycles endanger those around them while driving. One can't tell how far away they are when they are approaching at night because they have only one headlight, they get the aforementioned ability to pass me within my own lane when the traffic is slow so one has to worry about some jerk dragging some part of his bike down ones paint job, and they're much harder to see (especially the smaller bikes) while one is driving under all conditions.
And by the way, by the time I finish eating and talking, my glass of wine with my meal won't put me over the sensible limit we have in my state so your snide mocking in relation to me paying thousands to get to work is irrelevant. It must be a great view from way up there though, casting judgment and laughing at all of us poor sinners.
