About half an hour to get in if the weather is clear, maybe 35 to get home, as long as there is not the slightest distraction or disturbance. Apart from a mile or so at the beginning and end, my commute is basically travelling 90% of the length of I-696. If there is nothing impeding or distracting traffic, I whiz along at 80 and STILL get my bumper chewed off by some cat who wants to go 95. If three molecules of H20 should condense together and settle on the road, or some crusty old fart decides he is going to go 10 under in the fast lane and damn well teach us all a lesson, or someone pulls over to change a tire, or the cops decide that the busiest junction along the freeway (say Telegraph or I-75) is a jolly fine place to hand out a speeding ticket, the whole freeway freezes solid like somebody spread glue across it. At those times I feel jumpin out of my car and running around randomly and shrieking.
