Hmm. If you look at traffic, even in stop-and-go or at least nearly-stop-and-go… there’s so much space between vehicles, even though it doesn’t feel like it when you’re driving. I’m not sure smaller vehicles would do much for traffic.
That said, I support smaller vehicles for any number of reasons. I’m just not sure that’s one of them. :shrug: Disclaimer: Totes thinking about videos one sees of traffic and how much space there is. I could be wrong.
Yeah.
The current recommendation is 3 seconds. At 35mph, that’s a car every 175 feet, give or take. Calculating all traffic as being in 20 foot trucks/SUVs.
If everyone switched to Smart cars or that length, that’s about 9 feet long. So you have a car every ~165 feet.
You can fit five percent more cars on the road. Which isn’t nothing.
But it’s pretty damn close to nothing.
Shorter vehicles is not going to solve traffic, although it’s still better for other reasons.
In the best-case scenario of stop-and-go traffic, you’re probably looking at large vehicles every 50 feet and smaller vehicles every 40 feet. That is 20% more, sure, but you could also “just add another lane” for that sort of effect.
Also, the nature of traffic is that if you can handle more people on the road, people will commute farther and re-saturate the road (hence the “just-another-lane” reference above).
