Are they “cleaning” or just not producing as much dirty? Semantics…
worth defining tho.

Exactly. EVs are a band-aid, but the true cure is simply viable alternatives to driving .
Yep. I’m finally in a place to bike to work and elsewhere and it’s remarkable how much I can get done without a car. But the infrastructure sucks and there’s so much room for improvement.
Looking forward to your commute is so great. Have you treated yourself to a nice bike?

#73Works for modern trains, too. I was watching one of the new electric CALTRAIN multiple units pull into a station. The motors did all the braking except for the last few feet of stopping. The friction brakes normally go on below 5 MPH, and are rather noisy for disk brakes. Emergency braking is friction brakes only.
The brake dust from low-noise train brakes smells so incredibly nasty (burning ABS, pretty much) but the operators and OEMs claim it’s >. Bonus points for the Bombardier bi-level coaches, where the AC air intake is right above the wheelsets and takes a healthy gulp of that brake dust and smell and distributes it to the passengers inside (because the smell is just as pungent inside as outside a few seconds after coming to a stop I doubt the filters, if any, are doing much). Frankly I’d not commute with it.

Wrong.

It's the inverse. Bikes are a temporary 19-th century fix for the lack of easily available personal cars.
It took me 15 mins to get home 8km away just now. My colleague has a 500m shorter route and took 55mins. Cars are better?

Yeah, electric cars just are not practical for day-to-day use. They are toys for rich children. We should focus on producing actually clean and usable cars - using natural gas, not gasoline.
CNG and LNG vehicles have been around for decades and never really taken off. An interim measure and not really a path to net zero, either.

A lot of people need trucks for their work. Hispanics in gardening and construction in particular.
Europe has plenty of gardeners and construction projects too, but I see at most one pickup truck per decade and it is always someone who definitely doesn’t need one and drives like they’re in a mad max movie.
If you think all truck owners actually need one, count how many of the ones you see are carrying some load and do the math.

Do you know where the increased tyre wear comes from? I run a PHEV, and if anything, my tyre wear has improved. This being said, I’ve noticed that many a “big EV” driver will take off from red lights like they’re driving a dragster.
I think most reasonable explanation is likely very much increased torque and rather poor traction control leading to common slipping. Which directly wears tires. Hybrid vehicles generally have less torque so they have less this type of wear. Unless driven purposefully aggressively. Clear solution would be to limit acceleration of vehicles and mandate traction control that limits this type of wear.
I'm surprised EVs don't all have traction control since there's already got to be a computerized control loop for motor drive at that power level. And slipping is an obvious problem when max torque is at zero RPM.

- less safe in accidents for all other cars (electric cars are heavier)
My leaf is smaller than most cars.
- increased electricity prices for everyone
I use solar.
- tax payer subsidies
I wish.
- high upfront carbon cost
All cars are terrible at this, and I did not doubt EVs a terrible too.
- higher lifetime co2 emissions (until we build out nuclear)
Or solar, or wind, or hydro.
- charging infrastructure is poor, short lived, painful to use.
I plug it in at home. This is 99.9% of our charging. This is the best feature of EVs, we never visit petrol stations.
