Once you switch, it's hard to imagine ever going back. No more gas stations, dramatic drop in fuel cost, always ready to go fully charged each morning. I'm addicted.

Do you live in a house with your own dedicated charger? How does this apply to someone living in an apartment or other similar situation to not having dedicated chargers?

Sure, there will always be some folks that cannot, for whatever cause, enjoy overnight charging where they park. For those folks, it is essentially a lateral move. They can enjoy the performance benefits, of course, but their running costs and convenience probably won't be any better with an EV.

Who knows, though, maybe one-plug-per-spot will become enough of a selling point that apartment owners will start to deploy the infrastructure. I don't think it will affect EV adoption one way or the other, however, at least not for a number of years. Apartment dwellers are just a fraction of car owners.

Just for the record- it only takes about 21k miles of driving (a year or two for most people) to release as much CO2 as the production of the battery for a long range Tesla Model 3. The standard range Model 3 comes in just under 16k miles. It seems to me like most people expect more. Also, I don't think EV prices have really changed that much. Chip shortages haven't really affected it. High gas prices and inflation a…

Does this assume the electricity is emission free? Because where I live less than 40% of our electricity is from renewables (even those aren't completely 0 carbon impact, as they have to produce panels/wind mills/etc...). The rest is from oil & gas plants. I understand you are comparing driving an ICE vehicle vs. production of an electric one. But it seems a little misleading to ignore the co2 impact of driving the e…

One thing to realize is that EV's have significantly lower emissions even on a grid that has no renewables. Power plants are much bigger than car engines, so they lose way less energy to heat. Also, the grid is more efficient than trucking gas around to gas stations. All in all, an EV will use about half the fuel as a gas car even before you start looking at renewable energy. Also, EVs change where emissions happen which is a major win for air quality.

I wasn't suggesting to extend the comparison. I was saying that for the comparison done they were ignoring the environmental impact of driving the EV. Obviously EV comes out on top over a very long period of time. I'm just suggesting that period of time is longer than suggested by the parent. Personally I'd love to buy an EV but in our climate battery life is reduced by 30%, renewables are a low portion of our electr…

You are wrong to assume they are ignoring it, and irresponsible to state this assumption as fact.

Who is they? I was merely referring to the parent poster who did indeed ignore it.

Somewhat off-topic, but maybe someone knows. There's one thing that worries me about EVs: local pollution. So, ICE cars release CO2 + they release local pollutants (NO, CO, etc), particulate matter, that kind of thing. EVs obviously don't directly release CO2 nor do they release those local pollutants. However, EVs are on average much heavier (probably 200-400kgs heavier), which means that they probably need bigger t…

I don't have a specific study but regenerative breaking as used in commercial EVs would mean less particulate from breakpads etc. not more.

The question is reasonable and I'm not sure why it was heavily downvoted, tire wear and road wear depends polynomially on the vehicle weight (I remembered it's the cube, I tried Googling but Google has turned completely fucking useless for anything serious)

edit: it's the 4th power for road damage (!): https://www.denenapoints.com/relationship-vehicle-weight-roa...

As a Canadian who's currently driving a 9 year old Mazda 3, I'm waiting for the day it decides to call quits so I can move to an EV (9 isn't that old, so I'm hopeful at least another 2-3 years) That said, I wish there was a site that simply told me now's the right time to buy an EV. With supply chain issues, long waits for a new car, government rebates, and the influx of new inventory/models, it's hard to keep up whe…

"This chapter estimates the non-exhaust PM emission factors from electric vehicles and compares these factors with those of internal combustion engine vehicles. Assuming lightweight EVs (i.e. with battery packs enabling a driving range of about 100 miles), the report finds that EVs emit an estimated 11-13% less non-exhaust PM2.5 and 18-19% less PM10 than ICEVs. Assuming that EV models are heavier (with battery packs enabling a driving range of 300 miles or higher), however, the report finds that they reduce PM10 by only 4-7% and increase PM2.5 by 3-8% relative to conventional vehicles. Additional simulations indicate that the uptake of electric vehicles will lead to very marginal decreases in total PM emissions from road traffic in future years. In scenarios where electric vehicles comprise 4% and 8% of the vehicle stock in 2030, their penetration reduces PM emissions by 0.3%-0.8% relative to current levels."

With our last purchase, we went half-way and got the plug-in hybrid Chrysler Pacifica minivan (which replaced a Prius which replaced a Mazda 6 so it's been a continuous evolution). It's likely that the next car will be a full-on EV. Assuming you have an acceptable parking/charging solution available, a plug-in hybrid is a good option. The Chrysler uses gas more often in the winter to run the heater but even before th…

I'm curious if you've run into any issues (Or worried about) cycling gas that long. I know that gas can "go bad" over the span of 6 months - 1 year. Do you ever intentionally run the gas, just so you can burn some and put new in?

Gas doesn't go bad as fast as people pretend. Yes it has lost a bit of octane rating sitting around, but unless you are driving a 30+ year old performance engine with high compression your car isn't going to notice the loss of a few octane points. Anything within the last 15 years measures and adjusts for fuel octane rating automatically and won't care, and anything non-performance that is older was designed expecting fuel octane to be lower than what it is sold as. Also these days most places add 10% ethanol to all pump gas which has a higher octane than gasoline and is replacing some of the old high-octane components of fuel that evaporated and caused gas to go bad sooner.

If you live in a part of Canada that is pretty cold, I would do a lot of tests before committing to a specific car. I have a model S and while it's an incredible car, its range is about 40% less if I drive it up North. I live in SoCal though so I don't have issues.
