Every day it feels like we're getting closer to battery revolution. It really makes you wonder how different the world will be once we have these incredible batteries actually working at consumer level.
Can you imagine not having the constant traffic noise played into your ears like tinnitus, being able to maybe actually breathe the oxygen nature provides. That’s probably gonna be what it will be like. But still, ev are just a stop gap, more privately owned cars isn’t the solution in my humble opinion, it is a start towards it.
Totally with you, but tire dust is one of the major pollution particles from cars, maybe even the worst AFAIK. That, sadly will not go away but it is still leagues more desireable to have everything on electric than fossil fuel. Can't have perfect stop good enough.
Yep, tire pollution is even worse with EVs due to their weight. But overall it's still much better as you said.
It would help if cars went back to a reasonable size and not the absurdly large monstrosities that dominate the market today.
It's even hard to find an EV sedan. There are like 3 models under $70k. Everyone wants to make SUVs instead.
That's the real kicker. Gets especially hard if you don't want a Tesla.
Many of the conservatives who cite heaviness of EVs as a problem didn't say shit as ICE cars got heavier and they bought F150s to go to Walmart.
Yep, I'm all for it. However, they would be still heavier compared to equivalents ICEs.
There's no reason to think that will last. The kwh/kg of batteries improves by 5-8% per year, and we've been in the higher end of that range the last few years. Meanwhile, EVs are about 30% heavier. It will take a few years of improvement to make up that gap, but there's every reason to expect this trend to continue.
Also, it takes a few years for new batteries to find their way into existing models. 1.08^4 = 1.36, which means improvements in batteries since 2020 could have made up this gap already.
Yes, sure, batteries are evolving and there are solid state batteries on horizon, though probably very expensive initially. There is also a concept of getting energy wirelessly from road, which could further reduce battery sizes. I'm sure the future is bright.
The tire noise EVs make is about the same as an ICE car at about 50 kph (30 mph) so it doesn't make much difference on busy roads. It does make a huge difference in slow traffic.
It's not tire noise that bothers me, it's the folks who seem to think that the rest of us will think they're cool for being able to hear their engine roaring down the road from a quarter mile away.
They'll switch to very loud music unfortunately.
I would rather hear loud music than ear-piercing motor noise.
About noise, above 30km/h electric cars are as noisy as gas powered one.
It's better but not the panacea either.
Solution: 30km/h speed limit in cities, which is a good idea anyway for safety reasons.
Yes, it's better for safety and health reason.
Plus 30km/h is in the speed range of bikes, so it become much more accessible to bike around in the city and more people start to do it.
It’s 30mph not kph. City streets should be limited to 20mph anyway.
The traffic noise will stay the same, from tires, honking and some fake engine noise they'll mandate for pedestrian safety.
Do yourself a favor and spend some time in an area without cars. It's amazing what it does to your mental health.
Building massive production capacity to replace all the cars just locks us in to having cars though
