There’s no harm involved in going 10mph slower. It adds seconds or a couple of minutes at most to most people’s journey times. You say “lazy” as if an easy way to reduce accidents is a bad thing.
There is. I live in a city with 20million people, everyday a good share of them waste hours stuck in traffic, making it slower only worsened the situation.
Do you not think the problem is the hours wasted stuck in traffic than a slight reduction in the speed when you aren’t? I mean when you are in traffic your speed is 0 and the speed limit could be 1,000 MPH for all the difference it makes.
A faster speed limit means cars before the traffic jam start will spend less time on the roads, the less time cars spend out the longer it takes for a jam to start and the shorter it will be.
Or, to put it another way, a faster speed limit means drivers get to the next traffic jam faster, making it larger more quickly.
Traffic is a flow problem, what you are saying makes no sense. I dont think I will change your mind so we should end this discussion here.
Traffic flows best at 20mph. Here’s a scientific study that proves it (pdf warning)
Somehow, I don’t think you will change his mind, ironically enough.
They are not commuting through 20mph zones. That’s pants-on-head.
