One person leaving too much of a gap doesn't create 10 seconds x 350 cars delay. They add 10 seconds delay. You'd only get that hour if everyone had a 10 second

One person leaving too much of a gap doesn't create 10 seconds x 350 cars delay. They add 10 seconds delay. You'd only get that hour if everyone had a 10 second gap.
And nobody leaves a 5-10 second gap. That's huge. The DMV recommends something like 2-3 seconds.
- sandworm101 11y agoYou missed the point. I didn't mean they delayed any one person by an hour. They are delaying 350 people each by ten seconds ... a cumulative delay of an hour. 10 seconds on a bridge is not unusual. They are normally people looking at the view. The kids around here are taught to "Increase your following distance ... to four seconds in bad weather conditions." In Vancouver, that is a not-small amount of the year. http://www.icbc.com/driver-licensing/Documents/drivers5.pdf http://www.icbc.com/driver-licensing/Documents/drivers5.pdf At 75kph (normal speed on a rushhour bridge) 4 seconds means an 80 meter (90yard) gap. If everyone left such a gap any city would grind to a halt.
- vectorjohn 11y agoI didn't miss the point, I just don't think that's a meaningful number. What's meaningful is total throughput and each individual's time on the road. The 10 second gap doesn't much affect either. Also, presumably they'll close the gap or leave the road at some point, at which time cars could (shouldn't) speed up and save their 8 seconds. But it's that kind of stupidity that causes the traffic waves anyway, to save 8 seconds.
