I think that instead we will see cleaner air in cities since the economics of electric/hybrid cars will win, especially in city traffic. This trend can already be seen in SF where zero-emission hybrids and electrics make up a decent percentage of the traffic.
- ImaCake 6y agoYou talk about these things like they are the future. But western cities are already much much cleaner than 40 years ago. The move to electric cars and more livable cities is just the continuation of a fight that has been going on at least since the industrial revolution and adoption of hygiene.
- jdsully 6y agoLong before the industrial revolution. Horse manure and slaughter runoff were huge sources of disease in cities even before coal smoke took over the air.
- kqr 6y agoAs others have mentioned, personal automobiles are the problem, not the fuel they run on. Modern engines run rather cleanly. Noise, safety, rubbers and other particulates are also ruining the local environment.
- speedgoose 6y agoCome on, they run not clean at all. Have you smelled a brand new diesel engine during winter? Or even a bad self-polluting hybrid? Personal automobiles are part of the problem. Perhaps not the biggest problem but a big one in cities.
- fileeditview 6y agoI am not really disagreeing with you but one should add that bad smell is not necessarily a good indicator for what is unhealthy.. there are many poisonous gases without any smell (also emitted by cars).
- rtx 6y agoBreaks are the biggest source of pollution.
- reitzensteinm 6y agoRegenerative braking helps with pollution, since you're not wearing a brake pad, just running the motor in reverse.

- Klinky 6y agoDiesel is pretty bad, but a modern gas engine after warming up with leaner fuel mix and catalytic converter heated up has pretty tame emissions.
- vosper 6y agoI hope we will see cleaner air in cities! But the time it takes to replace a country’s vehicle fleet is sometimes measured in decades, and no-one is even starting on a project of massively reducing fleet emissions. I think / hope you are right in the long term, but I think I am right in the short-medium term :)

- jhoechtl 6y ago> I think that instead we will see cleaner air in cities since the economics of electric/hybrid cars will win Citation needed. The whole economic and environment footprint of electric vehicles in relation to their efficieny is rather bad. The future would the CNG but something is holding it back.

- lowercase1 6y agoNote that as much as 30 percent of car pollution is not from the fuel and would remain.
- Falling3 6y agoWhat is the cause of that ~30%?
- nkingsy 6y agoBrakes/tires
- karakot 6y agoit's nowhere close to true. otherwise you'd have to change your tires and brakes each time you visit a gas station.
- Fezzik 6y agoIt may be you who are mistaken: “...particles from brake wear, tyre wear and road surface wear directly contribute to well over half of particle pollution from road transport.” https://www.bbc.co.uk/news/business-48944561 https://www.bbc.co.uk/news/business-48944561
- trickstra 6y agoNotice how they specified "particle" pollution. That's a subclass of the general pollution. Small subclass.
- Fezzik 6y agoParticle pollution, if they are using it correctly, which I think they are, includes exhaust and pretty much every post-production pollutant produced by a car (before it is scrapped I guess).
