> Particulates issued from tailpipes can aggravate asthma and heart disease and increase the risk of lung cancer and heart attack. Globally, they are a leading risk factor for premature death.

Minor nitpick, but tailpipes aren't the primary source of emissions. The study is about PM2.5[0]. which will chiefly be tires and brake pads. Modern gasoline engines are relatively clean, outside of CO2, though diesel engines spit out a bunch of bad stuff.

How do EVs fare in this regard? Brakes are used significantly less, but the additional weight from the batteries chews through tires faster.

Why does everyone immediately pivot to EVs on this subject, instead of (looks around) gargantuan SUVs and trucks everywhere, due to peculiarities of US policies regulating SUVs more leniently than cars on fuel efficiency?

Because a lot if EV buyers are interested in the environmental impact of their purchase?

I say this as someone who owns an electric scooter and whose next car will be an EV—the sales pitch for EVs right now is basically pay more (especially now that the tax credit is gone) to have a worse time and maybe eventually claw some of it back over the lifetime of the car in fuel savings. The environmental impact is the pro in the pro con list. So if that doesn't pan out, or doesn't pan out enough it's going to be a tough sell.

Just the cost to get my garage outfitted with a charging port is about to be in the thousands because it requires me to replace the entire breaker panel. Now this is a me problem because that panel is ancient but it does add to the total cost of "doing this" and going EV.

…to have a worse time

Says the person who has never owned an EV. Fifteen years of EV ownership, I’m never going back. Environmental factors aside, an EV is the overall better vehicle. You can keep your rattling ICE vehicles that need special fluid from specific vendors.

I guess I should have said "a more inconvenient time" where owning an EV kinda revolves around your charging setup/schedule in a way that you don't have to think about with ICE cars. I know some people swear by them being more fun to drive but that's the last thing on my list of requirements for a car. I will say I think you're giving ICE cars a bad rap, my little Honda Fit that will be replaced by the EV is at 150k miles with nothing other than like three oil changes (yes i know) and a new set of tires.

I plug it in when I get home, and when I get in it again the "tank" is always full. I think about the EV a lot less than I do our ICE car, which seems to need gas at the most inconvenient times. You might have an argument for road trips, but even that's almost a no-brainer these days. Sure, I can't just get off at some random exit in the Utah desert and expect to find a charger, but my experience says this whole "charging on a road trip" is way overblown, as if even the slightest bit of look-ahead planning is just too much for people to handle.

Doesn't constant charging to 100% wreck the battery longevity?

“Full” meaning 80%. With a 300 mile range, that’s plenty for day-to-day.

But to your question: I don’t know, does it still? Seems BMS has gotten a lot better from the early Nissan Leaf days, so I don’t if it yet time to retire that along with “discharge batteries all the way so they don’t get ‘memory’”.
