You should still tip though. Or don't go to restaurants. All you are doing is taking your disagreement with the establishment out on the worker.

In the UK it is a thank you for good service, in the US it is a necessity to help your server pay rent and eat.

Do a google search for Tesla dyno graphs. You’ll see the power is virtually flat while the torque decreases steadily. It’s constant power output, not constant torque.

More like companies using it as an excuse to pay lower

I dont tip as i stand for paying people what they are worth

It's just societal norns that customers should be directly paying the majority of their wages, not the employer.

Any “constant torque” would be due to the fact that at low speeds you’re traction limited so only a fraction of the cars power can be used.

Once you’re no longer traction limited, the torque will steadily decrease and power output will be flat.

This is a Tesla S P85D on a dyno. Notice the torque peaks (at 864 ft-lb!!!!) then steadily decreases. The power is nearly perfectly level just above 400hp for the entire second half of the run.

Was pitched a company doing add-on electric drive for F-150 pickups. They had a few dozen on the road, it Was not just vaporware.

The motor was claimed to make 400hp and was a cylinder roughly 14 inches long x 11 inches diameter. I did not verify this claim. I don't recall the torque spec.

But to be fair to both EV and ICE, you need to factor in the battery mass and volume, against gas tank mass and volume.

This is the perfect eli5, there's superheroes and everything!

In absolute terms, they don't - both ICE and Electric vehicles are limited in acceleration performance by traction and tire technology at the top end. However, powerful small motors and instant torque do make it easier to build an electric car that accelerates quickly.

On the flipside, ICE cars have inherent advantages (mainly lower weight) in terms of top speed and especially handling, so electric cars that aim to be exciting tend to lean harder into the one thing they're especially good at comparatively and have developed a reputation for very good acceleration as a result.

They have basically constant torque (up to a point), but not power. Power output grow with rotational speed (power is torque times speed) , so the rated HP for electric vehicles can be extracted just before the torque drops of. A ICE also has low torque at low speeds, which is why they feel more sluggish to drive.

Electric peak power is at about 2900RPM there

Not exactly. In a rotating engine, power is engine torque multiplied by rotations per minute. Electric motors don’t produce peak power at all engine speeds, because in order to do that, they’d have to produce peak torque at 1 rpm and then have the amount of torque produced gradually decrease as the engine speeds up.

What electric motors do is produce consistent torque at all engine speeds. They still have a power curve, it just looks a bit different than an ICE.

With an ICE, you only get peak torque at a certain engine speed, and you actually get less torque when the engine is going too fast.

People are talking about the torque advantage of electric motors and while that does play into it, the superior performance potential of an EV is really about the power you can get out of small motors. Electric motors are far simpler to build. They're smaller and lighter for similar output than an internal combustion engine. So, you can pack more power into the car, and it goes faster.

Because an electric motor can handle faster revolutions than an internal combustion engine, you can also attach it to the wheels via a single speed transmission. So, while internal combustion cars are shifting, the EV is still just accelerating.

Internal combustion engine engine

Been explained already but I wanted to have fun with this one

Superman (electric engine) and the in this universe the clearly faster flash ( combustion engine) are having a race by pushing an extremely heavy train along a track

Well for Superman the weight is not an issue he just has to make sure not to rip through the train while pushing so he just pushes on the back of train at maximum force that won't destroy and steadily accelerates.

Flash is there with the problem of he is faster but weight is a problem... But with enough speed he uses the kinetic energy of a kick to get the train moving, then another and another

With each kick the train moves faster and faster and more energy is converted into speed.

Flash train now moving faster than Superman's but took a lot longer to get there

Internal combustion engine horsepower numbers a little bit misleading. The numbers they tell you are actually "peak" horsepower. A 2022 Corvette makes peak 490 horsepower at 6,450rpm. This means it makes less horsepower at every other rpm, most notoriously at low rpm's.

An electric motor makes its peak power ALL the time.

An ICE engine has a torque curve that builds from idle up to peak usually 4-6 thousand RPM later. It takes time to find that torque and that power.

An electric motor is nearly opposite. The second you apply the voltage it’s off, maximum torque like a switch. That combined with multiple motors to keep each wheel working at peak performance and use that torque leads to ridiculously fast acceleration.

Similar reason big diesel wagons can punch so hard, they have torque low down and available but as they drop off (like electric motors) that’s where ICE is going to catch up if at all. I recommend looking at dyno graphs for a few cars and you’ll see this graphically.

Let me know how the time travel works out for you. I’m going to buy coffee with dollars, will be back before you leave.

Please find me a bakery that will accept your gold. I’ll wait

You travel forward in time and even great empires fall. Someone will be a bag holder for all those investments. It won't be the guy with a pile of gold.

If the US, China and Euro bonds Canada has plummet, having gold is probably not going to help us.

You aren't really asking about gold, you're asking about fiat currency. Some people say that the US dollar (or any fiat currency) isn't real, has no intrinsic value, only exists because we say it does... this is not true. Fiat currency is backed by law and the state's monopoly on legal violence. To say that the dollar is useless is basically saying the US economy doesn't exist.
