Drunk people aren't gonna be coherent enough to check their phones for check points. Let's the other sane people avoid the added traffic.
Exactly correct. I am actually more afraid of someone texting while driving. Now that actually scares me more... and how do we stop that? Make handheld devices illegal! There, more lives saved. Outlaw the iphone, android, etc.
I would say outlaw all cell phones that have text capability (/sarc).
