EV general discussion

Agreed - much as I hate the obnoxiously loud exhausts some people insist on putting on their bikes (particularly the little **** round here who think it's acceptable to do laps of the area at 3am), it does make them "safer" in as much as people can hear you coming.
But a 200hp EV is the same. That’s what I get told when people compare the 0-60 on a EV to my e92 m3

I'm not sure you do hear them approaching in a way that's useful for safety.
"...The Doppler effect explains why motorcycles often seem to appear out of nowhere, creating a sudden roar only after they have passed, rather than being heard well in advance. This phenomenon, combined with how sound travels, means a rapidly approaching vehicle can be silent or quiet until it is almost alongside an observer..."
It depends on what you mean by motorcyclists though.
the kinds of bikes that you see around towns and cities work extremely well as EVs and massively cut down on emissions.
The evidence of this is really clear in Asia.
In stop start traffic when they’re filtering it is.
The context of the comment was driving a scooter in Thailand, not a land speed record.
I dont think any bike is breaking the sound barrier.

That's because they are up to 80% of road users in some Asian countries. Slight difference.
True but even in the U.K. context, the emissions they put out are pretty bad compared to car. I don’t mean CO2 but the really bad stuff like pm 2.5 particulates etc. and there are a hell of a lot of them concentrated into urban areas.

I'm not sure how much of that is perception than physics. In that we think we heard them earlier then we actually do.
"....You often cannot hear motorcycles in traffic due to a combination of modern car soundproofing, the directionality of motorcycle exhaust sound, and the high levels of ambient traffic noise. Despite the stereotype of "loud pipes," the sound produced by a motorcycle is largely projected backward, making it difficult for drivers in front of them to hear the bike until it is far too late ...
...Why "Loud Pipes" Don't Always Help
While some riders believe loud pipes increase safety, studies suggest they do not effectively alert drivers in front of them, particularly in heavy traffic where the sound is reflected and hard to locate. ...
Obviously people have different experiences.

Yeah i've always been very skeptical of the 'loud pipes save lives' crowd, i've never seen any evidence that it does as like you say the science seems to point otherwise.
If you want to be really noisy then just do it for that sake, you don't have to pretend.
As for EV bikes in urban settings then that'd be an amazing thing as bikes are far nosier than most other road users so it'd increase the quality of live for urban folks a lot.
Let's say I get something like the ioniq 5 with the big battery and during the week I wfh and don't do much mileage. Long trips during are at the weekend.
Can I get an ev tariff and charge my car to 80%(or whatever doesn't trash the battery) every night on the cheap tarrif and then use the ev to run the house during the day?
Is the battery likely to be sufficient for a normal wfh use case?
What kind of electrical setup do I need to get and what's it likely to cost?
We might move in a few years, so don't want to invest in a solar setup.
Thanks all!

That's disappointing, I thought v2h was a thing now.

Yeah, you need a Vehicle 2 Home.
Your Ioniq 5 can allegedly power up to 3.6kw of small appliances, though I've read other things saying it's 1800w max, but can't be substituted for your entire homes power.
I think the Kia EV9 does V2H

It is but requires specific chargers/cars
Tbf deliveroo and just eat delivery bikes are only probably 2mph behind the speed of sound.
