Yep, you get a lot of drivers in a hurry to get to work on a major highway and of course they're speeding also and mix it with some icy patch of road and you have the makings of a disaster waiting to happen. It hasn't dawned on people to leave early for work and allow extra time for traffic backups, lane closures, slow moving gawkers because they've never seen a person changing a tire before , train crossing, or even bad weather. I myself would rather be at work 20 minutes early than to be at work 2 minutes late, and where I had worked they don't put up with tardiness too often. Besides when I arrive early I have time for a quick cup of coffee and I can kick back 'til starting time. No stress at all.
