Simply from the weight they carry, the energy required for this. Supplying a large city is neither cheap nor easy, and requires dozens or hundreds of daily shipments from dozens or hundreds of logistics companies. The majority of these happen during off-peak hours, to reduce load on the highway network.
Lithium batteries still can't approach 10% of gasoline's energy density, so gasoline is mandatory for trucks, and will be until yet another new battery technology is not only discovered and brought to market, but mass-produced to the point that we have a battery-pollution problem.
> the low standards for pollution controls
Why don't they increase the standards? If people are dying there must be public outrage. Does Universal Healthcare cover pollution injuries?
> European governments being willing to ignore automakers who break the rules.
Are people protesting or working to change their governmental leadership? Or are they content to see their loved ones perish? If diesel cars are such a problem, why not outlaw these? Then only outlaws will drive them.
Do you have a source for particulates killing children in cities?

Too bad that correct number to look at is entire power system energy density (engine+fuel+transmission). Electric engines are a lot lighter so batteries do not need to have same energy density. > Why don't they increase the standards? If people are dying there must be public outrage. Your expectation of public outrage happening doesn't mean it happens. Even if people are dying. > Do you have a source for particulates killing children in cities? http://bfy.tw/Dayg http://bfy.tw/Dayg

- greglindahl 9y agoFor how people die from air pollution, you can start with https://en.wikipedia.org/wiki/Air_pollution#Mortality https://en.wikipedia.org/wiki/Air_pollution#Mortality For Europe's special problem with diesel cars, try Googling [europe air pollution diesel]. It brings up a bunch of good news articles. Lithium batteries don't have to approach gasoline energy density to handle local deliveries. Also, these trucks don't use gasoline, they are diesel. Again, where is your source for "the majority of pollution is coming from large trucks"?

- stephengillie 9y agoI was mistaken. I apologize. https://www.theguardian.com/environment/2015/oct/21/diesel-cars-emissions-toxic-pollution-than-a-bus-data-reveals https://www.theguardian.com/environment/2015/oct/21/diesel-c... > It found that heavy-duty vehicles tested in Germany and Finland emitted about 210mg NOx per kilometre driven, less than half the 500mg/km pumped out by modern diesel cars that meet the highest “Euro 6” standard. However, the buses and trucks have larger engines and burn more diesel per kilometre, meaning that cars produce 10 times more NOx per litre of fuel That is atrocious - that a single car could pollute 4x more than a large truck or bus - and it's a side of the VW emissions scandal which never occurred to me. How did independent emissions testing not catch this - or were OBDII outputs simply accepted as accurate? The Seattle region used to have mandatory emissions testing by an independent agency, where they probe the tailpipe. This was recently ended. Were VW cars programmed to fool this testing too?
- BoorishBears 9y agoNOx isn't the only pollutant involved in localized deaths from pollution, so it's very misleading to claim a car "pollutes 4x as much as a truck" based on NOx alone. Also, what does this have to do with the VW scandal? Your own article explains why the cars generate more NOx per mile. They are held to lower standards than the trucks and busses after those were "reigned in" in 2011. It's not some kind of defeat device, the cars are still within regulation
