I pick up a bad screw every year from careless Ute drivers with leaky toolboxes and have to throw 1-2 tyres in the bin. Tyre wear isn't that important to me.

> and have to throw 1-2 tyres in the bin. That's your choice. We jack the car, pull the wheel, extract the screws, and use a tyre plug kit. Howto repair tubeless tyres with plugs: https://www.youtube.com/watch?v=nCwWPlaghfs Tyres with inner tubes can also be repaired, that's slightly more involved.

depends where the puncture is. too close to the sidewall and you have to bin them. if they've already been plugged once and theu get another puncture its off to the bin.

Well if you have a Tesla, I believe you can sit in it and it offers games to play on its iPad to kill the time.

Everytime I fill my truck up, I’m at the gas station thinking “man, I wish I could just hang out here for two hours!!”

More like 20 minutes, but ok, not everyone likes that.

I would love to have gone electric (bought a car in September) but I rent and don't have any way to charge at my residence. How do we solve the renters-that-cant-charge-their-cars problem?

You could possibly have come to an arrangement about getting a 50 Amp (think dryer plug) hookup in the garage and provided your own charger. Also depending on your driving patterns a trickle charger in a 20 Amp socket may have worked for you as well. Mine takes about 48 hours for a full charge on the trickle charger.

There's no garage, and the only driveway-facing outlet is at the front door - opposite where my parking spot is allocated (an extension cord would have to go under/through the landlord's cars.) I have to drive 60km to work every day.

Only laws (accommodate EVs and/or WFH) or spending time sitting at a gas station will help me here. No landlord is interested in accommodating an EV unless it's a net benefit to them (and thus a net negative to me, who already spends 40% income just to have a place to work.)

If all of us renters were forced to convert to electric there’d never be an open charger in any city again for the next five years, because no landlord will voluntarily afford that cost, and no municipal region can pass a ballot measure to afford that cost. California’s impending ban of combustion car sales hinges wholly on a magical DC-charging network that doesn’t exist in U.S. cities yet (i.e. at parking meters),…

Level 1 charging overnight on a standard 120V outlet, while not ideal, is surprisingly adequate. Granted, many people rely on street parking or otherwise don't have a parking spot that is right beside their dwelling, but for rented houses or complexes with private garages/parking areas the size of the lift isn't necessarily "get upgraded service and a bunch of 240V EVSE put in".

I'll second this. We got a Chevy Bolt a couple of years ago, and I assumed we'd need to install a 240 V EVSE, but it turns out that regular 120 V 12 A charging is totally fine for us. I think there's been one time in the 2.5 years we've had it when we had to go to a nearby fast charger because the battery was getting low.

Of course if you're commuting 2 hours every day, things will be different. But for us, it's been great.

We should obviously ban combustion engine cars, at least starting with cities. I can’t think of a single clearer win for air quality.

Wow. Well, I like that the people that think like this also probably live I places where you are actually driving a coal powered car. Like the clowns in Hawaii that have extra subsidies for EVs… their power comes directly from burning crude oil. I’m an automotive EE, and and the truth about EVs is in a rush to push them out the door, the media and politicians have set the tech back at least a decade by pretending it…

While I think there is some merit to what you're saying, you're forgetting two major diferences between driving am ICE car and an EV charged on fossil fuel electricity.

First, EV engines are far, far more energy efficient than ICEs. Secondly, fossil fuel power plants are far more efficient at converting fossil fuels to energy than ICEs are (since the energy efficiency of a thermal engine is proportional to its volume).

The result is that the EV car mileage you'll get by burning 1t of oil in an oil power plant is much, much higher than the mileage you'll get from that same 1t of oil in ICE cars. I'm not 100% sure if this holds true for coal based power plants, but those should be getting relatively rarer.

Not to mention, fossil fuel power plants can have much better filters and some CO2/CH4 capture technologies, so the mileage you get per ton of greenhouse gas emissions is even better than the energy per ton of fossil fuels.

What are you doing to your tires that they only last 10k miles? I think that might be a driver error issue, because my EV (a heavier sedan) basically never needed tire replacement barring me running over a screw or something.

Just normal driving, it wasn’t quite so bad on our previous car which was a Nissan Leaf (with 30kWh battery) but our current Kia Niro just has a lot bigger batter (64kWh) and it is a lot heavier I suppose, the tyres just don’t seem to last as long. I’m pretty sure I’m using summer tyres all year round (I live in the UK) this was recommended by the dealer

remember, your regenerative braking comes at cost of tire life.

If driving Tesla, you can reduce the regenerative breaking from Maximum setting to Medium.

this will reduce regeneration and will increase the "breaking distance" when you just let go of accelerator pedal.

but it will increase your tire life significantly.

also make sure to buy the "commuter tire" models - tires with high mileage warranty (50k miles+) and harder compound. Even if it wears out faster, tire manufacturer's warranty will make up for it by giving you discount for the replacement tire purchase

I’m in the same situation, but I did go electric. I’m in a bigger city in Europe and the public infrastructure here is adequate and reliable. I rarely have to wait for the car to finish charging, it mostly fits my usage.

To some extent, but not really. Effectiveness of regenerative braking depends on having an extremely large battery that can sink enough current to stop the car. An EV can do that, hybrids at best help the brakes out some. You just can't charge the battery fast enough doing anything but a very slow rolling stop. My model Y can effect a very reasonable stop in traffic without touching the brake pedal except to hold the…

> My model Y can effect a very reasonable stop in traffic without touching the brake pedal except to hold the car at the end. My manual car could do this 20 years ago. My fully ICE motorcycle can do it today. I know engine braking is cool but it’s not some amazing new thing only EVs can do. Altho granted it only produces heat and noise in petrol vehicles. But it also makes your heart sing so that’s nice

The difference is neither of those generates gasoline on an ICE vehicle.

Well given Rivians rank among the worst EVs in the world efficiency-wise, maybe if you care about not spending your life at charging stations, don't buy a Rivian? Or a Tesla for that matter, since Tesla lies about their efficiency numbers and the real-world numbers are middling at best.

It is the low temperature performance that make most EV impractical. A Tesla power pack heater means the charge will be completely depleted if left outdoors for more than a week in winter. EV are meant for people that live in 4'C to 42'C weather, and have excess capacity on their solar installations. Everyone else is getting subsidized by their neighbors paying for excess electrical capacity. =3

Someone needs to tell all those people in Norway.
