Exactly. EVs are a band-aid, but the true cure is simply viable alternatives to driving .

I see men commuting in late model pickups down 880 and I think it'd be the same as me tossing a dollar bill out the window every mile.
Anybody who ever driven an EV, would have told that the initial scare about brake dust was pure nonsense. EVs barely use frictional brakes, with regen performing most of the braking action. Frictional brakes only really come into play to slow down from around ~5 mph to a complete stop. And even that can be eliminated by essentially running the motor backwards, at low torque. This mode of braking is sometimes used on…
How does this generally work wrt brakes needing to be used occasionally to not rust shut? Even with an ICE car if you don't drive a lot, and drive in a fuel efficient way (e.g. coasting towards red lights) this can be an issue resulting in an expensive surprise when you need to replace disks long before they are worn out.
Also, on EVs with LFP batteries the brakes do get used a bit more, because a full and/or cold pack usually can only take very limited power from regenerative braking. Depending on the implementation in the vehicle, brakes are either applied automatically to still allow for one-pedal-driving (aka. "brake blending", making the difference unnoticeable to the driver), or throttle-pedal regen is simply capped and the driver has to use the brake pedal when they notice that regen power is not sufficient.

I'm 99% sure this is a troll, but I hate to see misinformation go uncorrected. If this isn't a troll, you've been misled by fossil fuel industry propaganda, and I'm sorry. While EVs can be heavier, they often achieve high safety ratings due to their low center of gravity and robust battery protection. Advanced safety features are standard. Studies suggest that EV charging, especially when managed, can help stabilize…
It is not a troll. I was talking about safety for the drivers in the car that collide with the EV. They are less safe with EVs on the road. When we have marginal electricity pricing, and electric cars necessarily being marginal demand, then they will ramp pricing a lot for all users , not just those driving electric cars. This far outweighs the benefit of grid balancing services (which this green revolution has creat…
Unless you were stopped for half a day, that didn’t happen.

It's the inverse. Bikes are a temporary 19-th century fix for the lack of easily available personal cars.
Cars are a 20th century fix for the lack of easily available, comfortable, and fast public transportation. It's a shame the USA got stuck in the mid-20th century on that front.
And EVs are from the 21-st century. They are here to fix the utter inhumanity of dense cities, and eventually throw them into a dustbin of history.

Increased tire wear comes from the weight of the car and cornering. The tires need to do significantly more work in accelerating (the centrifugal kind) a car around corners at equal speed.
So obviously and logically speaking, an ICE car of equivalent weight should have the same tyre wear, and we know that's not true - there are some very heavy ICEs around which still manage to do 50k miles on a single set of tyres without any issue. EVs have instant torque from 0rpm and people use it and that's the main reason. Case in point - we have a Volkswagen e-Up, it barely weighs 1000kg, it's pretty much one of…

I'm glad that they address the increased tyre wear pollution. I'm not entirely(!) convinced that EVs only have slightly increased wear as there seems to be plenty of reports of EVs going through tyres a lot quicker though estimates do seem to vary from about 30% to 50% more wear. (Also great that the report mentions the importance of walking/cycling for city transport)
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.
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.

Never had any issue with rust.
