so electric domestic cars are not going to do a lot...
- NonContro 5y agoIt will still remove a significant amount of noise and air pollution from the ground-level of cities.
- jokoon 5y agoat 50km/h air friction with tires etc is half of the noise, and it goes from there.
- soperj 5y agoIf you've ever listened (from the outside) to an electric car going 50km/hr even, they're not quiet.
- jeromegv 5y agoI live next to a boulevard, 5th floor. The amount of black stuff that gets onto my balcony every day is absolutely insane. And to think that we are breathing that! I would fully embrace a full conversion for electric vehicle for that alone, this isn't just CO2, this is our air quality in cities.
- azinman2 5y agoKeep in mind that electric cars still have tire and break dust. Its not all tail pipes, tho clearly it’d be great to eliminate that.
- blendergeek 5y agoDue to regenerative breaking, electric vehicles (well at least Teslas) rarely use the breakpads, so less break dust. Tire dust will still be a problem.
- azinman2 5y agoMy VW ID.4 has two different breaking modes, one doesn’t use regenerative at all and the other is not nearly as aggressive as Teslas. Probably overall it’ll be less, but I expect variation depending on the manufacturer and consumer preference.
- beefalo 5y agoThey are even louder than fuel burning cars over 50kph due to the extra weight. I would still rather hear loud tire noise than breathe exhaust as a pedestrian though
- asdff 5y agoDue to the extra weight you also breath in more tire dust.
- hutzlibu 5y agoDo you have numbers to back that up? I can hear ICE engines accelerating roaringly from miles away. I do not hear the same from electric cars.
- beefalo 5y agoThe test in this video demonstrates it https://youtu.be/CTV-wwszGw8 https://youtu.be/CTV-wwszGw8. Obviously this applies to the ~average~ car. A hellcat or sports bike tearing down the highway will be louder but the consistent drone of tire noise increases slightly for electric cars.
- hiddencache 5y agoIs that a bad thing? Warns pedestrians...
- soperj 5y agoPrevious comment talks about reducing noise pollution.
- asdff 5y agoThey still contribute a good amount to localized air quality since there is still tire particulate at play, and these vehicles tend to weigh more than a given ice car of the same class.
- azinman2 5y agoI’m not sure where you got the 12% number from as I’ve seen other numbers. But regardless it’s an AND game, not OR. We should be minimizing everything simultaneously, as all those gains add up. It’s also not like all changes will be a step function either, so as things gradually change we absolutely need the addition rather than waiting for certain CO2 sources to become 0%.
- Someone 5y agoNothing in itself is going to do enough. We have to decrease emissions significantly, so that has to happen by making lots of small cuts. I think we have to make cars more efficient, make them smaller _and_ decrease their use.
- jillesvangurp 5y agoSo, your argument is that double digit percentages are not worth it? I'd say that's low hanging fruit. A no-brainer. Get it done and then worry about the rest separately. By the way, it's not just cars. Basically most forms of road transport can be electrified. Everything from the largest mining trucks, long distance trucks, short distance delivery vans, garbage trucks, delivery vans, etc. Viable products already exist in each of those categories. We just need more of them. Making more will make them cheaper and even more viable. The main bottleneck here is production capacity.
