I've alluded to this before on Hacker News, but the supposedly residential road that I live on is wide enough to fit approximately 7 full-size Hummer H1s side by side. The posted speed limit is 30 mph, and just riding with my elderly father-in-law today I noticed he was going 45 mph and being tailgated. I have personally lost a (thankfully parked and unoccupied) car to a collision, which wound up 100 ft down the road from where we left it. Many garbage cans have also fallen victim over the years. Calculations and considerations are all well and good, but when the rubber hits the road, wide straight roads will lead people to reason that it's fine to drive fast. I'd much, much rather have people think it's a pain to take my road because it's too skinny than to have 50-60 mph traffic accidentally kill my son or my neighbors when they choose to go outside.
