Another way electric cars clean the air: study says brake dust reduced by 83%

#12I'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.

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 or even lower electricity rates for everyone by improving grid utilization.
Many new technologies, including EVs, receive initial support to foster adoption and scale production, similar to past support for other industries.
While EV manufacturing has an upfront carbon footprint, their lifetime CO2 emissions are typically lower than gasoline cars, even with current energy grids. This advantage grows significantly as more renewables are added. Hybrids are a good step, but full EVs generally offer a greater reduction in emissions over their lifespan.
Charging infrastructure is rapidly expanding and improving in reliability. Typical daily driving is well within the range of modern EVs, and charging to 80% is often a time-saving measure for DC fast charging and helps prolong battery health, not a fundamental range flaw. Preconditioning optimizes battery performance but the energy used is a small fraction of overall capacity.
Efficient hybrids have their place, but EVs represent a significant step forward in reducing transportation emissions and improving urban air quality.

#14To those wondering about tire wear: "Despite the slightly higher levels of tire wear from EVs, brake dust was found to be more unhealthy, as brake dust is much more likely to become airborne (>40%) than tire wear is (1-5%). So EVs create a lot less of the worse thing, and a little more of the less-bad thing."

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.
Case in point - we have a Volkswagen e-Up, it barely weighs 1000kg, it's pretty much one of the lightest cars on the road. And yet it goes through its front tyres like nothing, and that's despite very modest power output of only 80bhp. But I do accelerate hard as it's so easy to do - so it's reflected in the tyre wear.

All else equal, the higher rate of BEV tire wear is primarily a function of their greater weight relative to comparable vehicles.
That's equivalent to those high school physics exercises that say "assume zero friction and no gravity". Everything else isn't equal with EVs because they make accelerating from standstill so effortless without any obvious downside that people do it back to back like it's nothing, while in an ICE you'd have to drive like a madman dumping the clutch every time just to get the same torque at the start. If you had two cars accelerating at the same rate then sure, the heavier one would wear out its tyres faster - but that's just not how people drive EVs(broadly speaking).

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.

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 created the need for).
I think you are not informed on the cost of renewables and therefore co2 cost. Just look at interconnection fees in the US. They have until recently got off for free on being added to the grid, but there was always a cost they imposed on the grid they didn't pay for. Now they have to pay high fees, and therefore high co2 costs to upgrade grid infrastructure.
My experience, in the UK and Europe, with ev infrastructure has been pretty terrible, especially when compared to just filling up with petrol. The cost advantage is also disappearing fast especially at public charging electricity rates.
Efficiency above 80% is clearly worse than below 80%. I drove 30k miles in a Tesla on road trips and saw that consistently.
I forgot to mention that once I lost 3% battery in waiting in the heat and air conditioning at a border crossing one time. That glass ceiling is not a good idea in hot climates.
