EV’s greatly reduce brake wear. We live on a mountain, and typically apply the brakes for 1-2 seconds to get down with the EV. We ride the brakes for 1 or 5 minutes with our manual or automatic transmission ICE car. Put another way, we’re pushing 50K miles on the EV’s original brakes and replacing / servicing them isn’t on our radar.

However, the EV eats tires like a full-size pickup truck with somewhere to be.

Out of curiosity, why is that?

Edit: I Google’d:

“ Electric vehicles boast instant torque, meaning they accelerate the second you put the pedal to the metal. However, the high instant torque of electric vehicles can also increase wear and tear. In addition to good grip, the rubber compound used for EV tyres also needs low rolling resistance.”

And

“ Teslas are heavier than most other cars because of their battery packs, which can add hundreds of pounds to the vehicle's overall weight. This extra weight puts additional strain on the tires and leads to increased friction between the tires and the road surface, which causes them to wear out faster.”

"Compared to a similar ICE vehicle"

It maybe a false memory effect but I vague remember this notion about trolleybuses.

No way, the grip on a normal road with those tires would be terrible. They would also be destroyed very quickly. They are designed for off-road low-speed applications. Low rolling resistance rubber tires are much more efficient energy wise as well. Rubber tires are very advanced anyway, many use chlorobutyl blends and steel and/or Kevlar reinforments.

That seems like a temporary issue. Right now we've still got lots of expensive/high class EVs where ludicrous mode is a thing people are excited about, but once there's real competition on the low end... "doesn't waste tyres" sounds like both a good selling point and simple to implement.

I think we are already there. The best selling Tesla right now is also a slowest Tesla ever made - Model Y SR at pretty limpy 0-60 of 7s (which is perfectly fine and fun to drive).

p.s. Seeing how many people already killed themselves with Plaid - I think gov should require advanced driving licence for super quick and super fast cars.

Re:The grid isn’t ready for 300M EVs by 2030 by rgmerk on Saturday May 06, 2023 @11:37PM (#35847695)
Advanced driving courses have a decidedly mixed record on improving safety, unfortunately. I believe the evidence suggests that they improve confidence more than they improve skill.

As for the Plaid, from what I’ve read the yoke and the high-speed handling are frankly dangerous. If somebody gave me one, I’d sell it and buy something where the drivetrain, the handling, and the aerodynamics are better matched.

I am under the (maybe wrong?) impression that the former issue is helped a lot by telling the car to accelerate in Chill mode instead of Standard, which causes it to purposefully carefully ramp a derivative or two of acceleration.
Re:The grid isn’t ready for 300M EVs by 2030 by hedora on Saturday May 06, 2023 @08:43PM (#35846743)
It helps less than you’d think. Part of the issue is that the tires are ultra low rolling resistance, and part is that the car weighs an extra ~500 lbs.
Re:The grid isn’t ready for 300M EVs by 2030 by saurik on Saturday May 06, 2023 @10:33PM (#35847343)
The car weighing a lot is the second issue, though, not the first. Is the ultra-low rolling resistance a third issue, or related to one of the other two?

It seems like this factor could be easily solved with torque output adjustments, but it won’t be unless it’s regulated.

The unwashed masses now expect every BEV to be performant without knowing the maintenance costs of actual ICE performance cars.

Manufacturers feed into this, as dealers love to have repeat customers for an otherwise low-maintenance car.

Re:The grid isn’t ready for 300M EVs by 2030 by lazide on Sunday May 07, 2023 @01:37PM (#35853715)
Huh? BEV maintenance costs are way lower than ICE, even if brakes and tires need replacing a little earlier than the ICE equivalent.

It’s just too hard to resist pulling out of an intersection with lots of acceleration. I’ve more than a few times heard my wheels squeal going from stop to 25 in a couple seconds.

50k is nothing, ICE cars often go longer than that without new brake pads. Had my ICE sedan for five years with no sign of brake squeaks yet. Never thought about brakes when I lived on a huge hill either.

I think most EV drivers will tell you that they use the brakes very infrequently - perhaps once or twice per hundred miles if one is driving long distances. Certainly if you're careful it'd be possible to never use the brakes. I think that's what EV owners think of as different to traditional cars. Yes, brakes can last a long time on traditional cars, but it seems intuitively obvious that if you're just not using them, they'll last longer for the same equipment.
Re:The grid isn’t ready for 300M EVs by 2030 by porkbeer on Saturday May 06, 2023 @11:30PM (#35847651)
Manual transmission drivers say the same.

The OP lives on top of a mountain. Brakes don't last 50k if you have to ride them for 5 minutes every time you leave home.
Re:The grid isn’t ready for 300M EVs by 2030 by porkbeer on Saturday May 06, 2023 @11:30PM (#35847643)
If you ride your brakes down a mountain, you are doing it wrong. Engine braking predated electric cars by quite some margin.

You should never ride the brakes for minutes at a time! Even if didn't care about wear, the main problem is they will overheat and become less and less effective so if you suddenly need to brake harder during that downhill, you may have little to no braking power.

Always use engine braking if faced with a long steep downhill. Use the brakes occasionally to modulate speed but never ride them continuously for a prolonged time.

We can excuse the brake riding in the automatic, but why not just downshift the manual?
