The impact car emissions have on the working poor is far more costly and dangerous.

And I doubt raising the tax rate on fuel would do much at all, in America at least. Gas prices have gone up significantly over the last few decades and we drive more and more.


Can't reply because of HN time restrictions on long threads, but I think the reduction on driving is more due to cities and housing centers within cities getting denser - even Houston is doing that, and we've traditionally been very spread out. We still are, but it's improving.


Actually we drive less and less per person since ~2004. And the total Vehicular Miles Travelled has been the same since 2004, even though population is growing. This is a significant trend. http://www.theatlanticcities.com/commute/2013/07/yet-more-ev...


That's not really true. During the gas price spike a couple years ago I do remember several articles that showed that we drove a lot less when the prices were higher.
