You can't compare the population and land mass of the US to any European country. There is too much of a logistics difference to show any similarity.Comment

Man, every single discussion on this board seems to spin way off the original topic. I guess I shouldn't reply once it gets this far from the original topic, but here's one last tidbit.

If hybrid trucks can use overhead wires to recharge on the go, and thereby reduce emissions and the number of days per month with unhealthy air in LA, that's significant in and of itself.

The ports of Long Beach and Los Angeles emit a lot of smog, and some days it sits in the local air basin, building up to levels well above the legal limit; see e.g.

Trucks are only part of the sources the same article states ships themselves, cranes etc are diesel powered and produce a lot of exhaust.
The article mentions 85% reduction in pollutants due to ports environmental efforts. Now it would be scientific to ask a question if those efforts actually affected death rates and by how much but that would be too common sense.Comment

Another study, "Assessing air quality and health benefits of the Clean Truck Program in the Alameda corridor, CA" (see scholar.google.com/scholar?cluster=16499385662035711114 ), looks into the question you raised.Comment

Basically, I'd suggest such a move would involve dedicating 2 or more lanes to driverless trucks powered by grid electricity via dedicated lines/rails for intercity and on board battery storage for local deliveries.
Look, this whole thread is more of Dan's usual kind of "you could just do this and voila', problem solved" simplistic nonsense/crap that folks like Dan are masters at dreaming up, and remind me of the (usually) drunken B.S. session stuff we'd dream up as students. The wiser of us (and not necessarily me) knew the devil is in the details. This kind of stuff belongs on the cover of Popular Science from the '70's, or some junk science forum.Comment

Are you saying they measured emissions wrong?Comment

Hey, I just wanted to post about Nevada's net metering. If folks want to talk about electric trucks and reduced pollution, though, fine.
I've separated people from employment for that type of disruptive and wastefully useless behavior in the workplace.
Feels good huh to be an agent of chaos huh ?
Your behavior around here is mostly like a pimple on the "nose" of progress. Besides, it's also inconsiderate and rude.Comment
