> public transportation A great idea that I am in support of, but it's not a "realistic alternative", public transportation is politically fraught, expensive, and slow to build in the U.S. I'm not saying we shouldn't continue to strive towards it, but it's not happening any time soon in the U.S. > ride sharing This is the status quo. > making streets more pedestrian friendly Same issue as public transportation - slow, expensive, politically fraught, but also of dubious ROI in terms of preventing DUIs; nobody is going to walk 5 miles home from the bar because of streets that are friendlier to pedestrians. Of course, there are other worthy reasons to create pedestrian friendly streets, but they don't really represent a realistic alternative to someone prone to intoxicated driving. > denser zoning Again, not really a realistic alternative, zoning issues are politically and economically contentious at a level that transcends concerns about drunk driving and yet the needle on that issue barley moves due to NIMBYism and entrenched special interests.
