They muffle slightly, but removing the cat alone isn’t going to make a big difference with modern high efficiency single cat exhausts.

I’ve seen (heard) the effects first hand. Trust me, people aren’t removing the cat just to make their car annoyingly loud. If they are, they’re going to be disappointed.

I know a LOT of people personally who swap their exhaust in and out just for emissions inspections. That's the meta.

The internet classic “I know a lot of people” does not substitute for your original “A lot of Americans” claim

You’re describing your small friend group, not Americans in general.

Speaking of smells.... One good thing about driving an EV is that weird oil or hot coolant smells are from someone else's car (and not a problem with your car) (although yes technically many EVs have coolant loops)

As the fleet of EV's age, I'm sure we'll see equivalents... "The high voltage wires were just dragging on the street sparking, presumably with all the safety features disabled" "They were driving with a 10 gallon coolant tank on the roof, presumably because the coolant loop had a big leak and needed continuous topping up".

If your high voltage line is conducting enough to the ground that it's sparking, your vehicle isn't going to work. Electricity follows the path of least resistance and a path to ground is a lot lower resistance than a motor coil.

EVs eliminate a lot of polluting failure states of ICE vehicles. There just simply aren't that many things to burn or leak and still have a functioning vehicle.

Well, if EVs are made mandatory we'll have even less air polution because fewer people will be able to afford a car. The auto industry seems to have ran out of early adopters already. Now they need a kick in the privates to make cheap EVs.

Chinese EVs are much cheaper then traditional ICE cars.

... for now. They're starting to be taxed.

Also, someone who doesn't think in SV lattes may not afford to buy a car with unknown reliability.

No surprises. No matter how we look at it, EVs are much friendlier and safer to the environment. Some people argue the source of electricty can be contested against because that involves fossil fuel burning again, but in today's world we are rapidly moving away from it and towards nuclear/hydel/wind methods for generating power. I hope ICE cars completely become a thing of the past in the next couple of decades to co…

I'm all for EVs, but half of PM10 pollution is independent of engine type as it comes from brake and tire wear: http://publications.jrc.ec.europa.eu/repository/bitstream/JR...

So direct environment impact is still huge for EVs and calling them ZEV is literally a scam.

You mean we can do something today that will reduce PM10 pollution by half?!

That’s fantastic news!

We could. We could massively fund public transit and massively reduce private car ownership. But we won't, because then capitalists will make less money.

That is not the argument being made. We are discussing how "dumb" vehicles (e.g. vehicles that contribute to 50,000+ fatalities annually) provide independence, privacy and freedom that "smart" vehicles (e.g. vehicles with self-driving that can be bricked at will) do not ensure.

Also you are conflating thing the poster may not have intended. I’ve not heard anyone complain about collision avoidance systems, antilock brakes etc. But spying packages, and touchscreen dash, hell no.

I hear people on this site complain about these things all the time.

Yes, that's why regenerative braking, which only EVs have, is so useful.

Lots (most?) cars are going to LCDs for the instrument panel. The second screen is the infotainment.

My previous car had its infotainment system reboot several times while I was on the expressway. The idea of my instrument panel, or other more critical systems, crashing and rebooting while driving terrifies me.

I've had multiple vehicles have instrument cluster failures while operating them. None of those have been screens. "Analog" gauges have not actually been analog for a while. They're all digital controls being read by a computer.

Even a carbureted motorcycle I owned from the early 2000s had "analog" gauges with values given to it from a computer!
