If you are driving an hour both ways every day in a cold climate, yeah, EV probably isn't the right fit for another couple of years. It's also an extreme end of usage. I imagine that a large portion of those people in a rural community don't drive more than 60 miles a day. It is also why the average commute per a person is not 125 miles but substantially less in the US. For reference, 125 miles is about Louisville, K…

125 miles is nothing in the US. It's not about commuting, it's about road trips to the next city, the next state. Sure most people are not doing that every day but they are doing that a few times a year to visit friends, family, and for business. And then what? Meticulouly planning your charges and timing your breaks? or taking a bus or a plane? If you've just spent $50,000 on an EV I would imagine you want to drive…

If by meticulously planning you mean using a navigation system that most EVs come with, I don’t see why this is hard? Sure, Tesla provides better routing software than EV manufacturers, but this isn’t a hard problem (this is HN, so we should have some affinity for software).

The road wear is said to be proportional to the fourth power of axle load. http://www.cyclelicio.us/2014/fourth-power-rule-road-tax/ That means you deal twice the damage by increasing weight by only 20%. Seems in line with electric car weight difference.

Yeah, that's my point. A single garbage truck is going to do more wear on the roads than thousands of passenger vehicles. Anything besides industrial vehicles is negligible.

Are there EV drivers that do not? I don’t think I could ever go back to using 2 or 3 pedals.

I only use one pedal in stop and go or city driving. Otherwise it's harder to maintain smooth speeds and is less efficient than just coasting.

Cruise control should solve that problem no?

Just did a 1000km (and back) drive this week, using a Kia Niro, which does about 400km on 64kWh. Was amazed I actually managed to drive this distance with 4 charges one way, and just 3 on the way back, reaching almost 400km actually on the first leg of the return trip (though this was downhill from the Alps). With longer roadtrips you want to go way below 20% remaining charge. With the quality of the charging-network…

That's not really amazing. That's a massive waste of time. I got 260km per charge in Enyaq iv80 going 130km/h on highway so cca same as you. That's 2 hours of driving and 1 hour of charging on 150kW+ charger.

A garbage truck has many tires to distribute the load. Also they accelerate/decelerate differently.

The author says his average mileage is 184Wh/km. I've seen similar numbers in other sources: about 200Wh/km. I am an avid cyclist. When I output 200W for an hour I can go 20-30km depending on the terrain. Maybe 15 if it's steep uphill all the way. Cyclists are not very aerodynamic. They sit high and have boxy shape. A small vehicle can be much more efficient (the reason recumbents beat standard bikes on a track). It…

Wouldn’t you rather want to compare manually operating a bicycle to an electric bicycle? They’ve basically taken over China for more than a decade now, so it’s not like they are uncommon.

E-bikes are fine. My point was that bikes are not very efficient because of shitty aerodynamics. A light, low and narrow electric vehicle would be more efficient and more palatable to a lot of people than bikes.

"couple of pounds heavier"??!?! That's understating it. Seriously, a Model 3 is ~500 lbs heavier than Honda Accord, and a Model Y is significantly heavier than a Model 3.

Typo, fixed. I could have sworn I typed "couple hundred pounds". But to your point, a bmw 430 is also around 500 pounds heavier than a Honda Accord. Nobody sees a BMW and freaks out about tire wear. But people seem to hyperfixate on any small negative of EVs.

> But to your point, a bmw 430 is also around 500 pounds heavier than a Honda Accord.

At the heaviest weights, yes, but the heaviest Accord weight and the lightest 430i weight are only 148 lbs apart... and the Model Y can weigh in almost 400 lbs heavier than the heaviest of 430i's.

> Nobody sees a BMW and freaks out about tire wear.

You mean, so long as it's not an EV? ;-)

Seriously, nobody freaks out about a BMW 430i's tire wear, because that of the branding of the car. It's like freaking out over coffee increasing your heart rate.

> But people seem to hyperfixate on any small negative of EVs.

We're obviously talking to different people. At least the folks I know talk about how crazy heavier cars keep getting across the board (case in point: https://www.capitalone.com/cars/learn/finding-the-right-car/...).

Model Y in cold climate here. While the sticker estimates of range are probably advertising, and the % battery to range meter you get in the app / dashboard is junk, the drive estimates are spot on . When you enter a destination, it will tell you very precisely how much energy it will take, accounting for every current condition, including temp. This must surely be data driven because it is alarmingly good. So your d…

For example, when driving a long distance (150m+), it told me that I could have saved X miles if my tires were inflated another 5psi, and saved Y miles if I had used less cabin heating.

You don't need to have the one pedal driving enabled to reap the benefits. In all EVs and PHEVs you brake with the electric motors first even when using the actual pedal - normal brakes are engaged only past a certain threshold. Also to give a personal anecdote, in my Volvo XC60 PHEV, I've just had the inspection done and after 24k miles the brake pads are 5% worn. That's insane for a 2.2 tonne SUV with 400bhp. If it…

> you brake with the electric motors first This is not true. At least for Teslas, the brake pedal only controls the friction brakes (they are hydraulically coupled). Same with a Chevy bolt. Unsure on other EVs
