Like Jimmy Carter's 55, this forces a lot more cars on the road at any given time.
Flying slower means more planes in the air at any given time as well.
Makes everything more dangerous, so they are saying ;Safety be damned'
THe problem with Carter's 55, is that it did take longer to get from point A to point B. Accidents actually increased out this way, because someone who was used to making a 600 mile drive in one day now had to be on the road for two more hours to make it. People were falling asleep at the wheel...
With that in mind, it makes no sense to speed in town. The risk profile from 30 MPH to go 10 minutes across town vs 60 MPH to get there in 5 minutes is nuts...BUT, on the interstates and on the long haul, the time saved by just 10 MPH over the limit can mean another 100 miles or more in a day's driving or just getting there a couple of hours quicker. Reduced fatigue generally translates to safer driving. Where interstates have reasonable speed limits, and being one of those busy covering distance, I have been known to make over 1000 miles in a day.
