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

In Teslas, any time your foot is completely off the accelerator, you're getting maximum regenerative braking. If you then press the brake pedal too, you're getting maximum regenerative braking plus friction braking.

EVs make substantially less of that, due to regenerative braking.

What portion of drivers use one pedal?

My Model S is approaching 90k miles and I have not needed to replace the pads. It has two pedals.

Interesting that driving style has such an outsized impact. Perhaps aggressive driving and tire composition should be regulated.

probably more effective to regulate the weight of vehicles by use than to broaden the definition of reckless driving. for safety, too

EVs do much better in stop and go traffic. I wouldn’t be surprised if some even exceeds EPA range estimates in those cases.

I doubt it would outperform EPA estimates (you can only recapture energy not create it afresh with regenerative braking), but compared to ICE cars the percentage of stated range would be very high.

The Chevy Volt PHEV had an estimated 53-mile all electric range. During the summer, I routinely got 56-60, and once got 67.5 miles before the engine had to kick in.

For occasional commutes, 115km one way is ok (not for me, but it's not unthinkable). But 115km each way (230km round trip) 5 days per week is a problem. We should not be doing this, at least not in individual cars. That electric car is still creating a lot of particulate pollution from the tires on the road, not to mention its contribution to general traffic. The focus should be on how to reduce the commute distance…

And their increased weight makes them much harsher on roads than normal cars. They wear down roads faster, and I suppose they also produces more particle pollution than normal car for this reason.

This just shows another reason EVs are unrealistic at least in rural USA. 200 km or 125 miles in cold weather. And that's for a Tesla a top of the line EV. Even if you live in the city most people want ability to travel long distances. I just reviewed consumer reports reviews of EVs. Not at all impressed. Overall ratings were very low for most cars. Charging is proprietary for the most part or slow or just in general a hassle. To get decent reviews you need to spend $50k at minimum. The tax rebate may help to extend the fantasy for a while but even Tesla owners are getting disillusioned. For the most part Tesla has saturated the market for high end EVs and the rest are low quality or suffer technical problems. I mean the vision is enticing but most Americans won't put up with the expense and hassle. And attempts to legislate the hassle won't bode well for politicians or will result in the predictable deadline extensions. And this is not even taking into consideration the extreme burden it will put on the grid which is not at all prepared for hundreds of millions of electric vehicles.

So you deliberately don't charge the battery to 100% then conclude the realistic range is shorter than advertised? I get you don't charge to 100% every day, but if you know you're going to drive further then....you do. Or just do what I do and charge to max each time, the battery is warrantied for 8 years, it's going to be fine. >>Imagine your daily commute is 115 km (e.g. Roeselare-Brussel That would be an extremely…

> What percentage should I charge the battery to? > > For regular use, we recommend keeping your car set within the 'Daily' range bracket, up to approximately 90%. Charging up to 100% is best saved for when you are preparing for a longer trip. You can adjust how full the battery charges from the charge settings menu. > [tesla.com/support/home-charging-installation/faq]( https://www.tesla.com/support/home-charging-ins…

That's only true of NMC batteries, not of LFP ones, which their Model 3 SR now ships with. With LFP batteries, it's better for them to charge them to 100%.

While EVs do use less brakes than ICE, they still should last a lot longer than you give them credit for.

Of course it's depends on how you drive, but if you are not getting 100k miles out of your brakes the problem is not the car but the driver.

If you look outside of the USA lots of cities have good public transport systems that aren't plagued by poverty, crime, homelessness and mental illness. Just because Americans have decided to optimize their society to maximize misery of a minority for the benefit of an even smaller minority doesn't make it necessary.

Transit isn't plagued by those here either, but a tiny minority gets a lot of attention.

Threads like this read like EVs are double or more the weight of an ICE car.

EVs are a couple hundred pounds heavier in average than an equivalent ICE car. In terms of road wear, it's still a rounding error compared to industrial trucks.
