If it pull less current, you can use batteries which aren't specced for high amps.
If use use less amps, you can use thinner cabling and split the batteries up i various compartments. That means heat is more distributed. Less active cooling, if any, is needed, of both batteries and motors.
All of the above can translate to less weight, which mean better range.
I meant for normal highway driving, not drag racing.
Optimal highway driving is still lowest resistance and losses. Cold weather driving is what mostly results in a battery capable of the high performance, from what I understand.
Is a "small" motors more efficient than a large one? I suspect no, with the assumption that everything is sized so the "drag race" operating range would be well into the peak, rather than sustained, operating range.
In my observation the primary purpose of this performance seems to be to be able to round on-ramps at really slow speeds and then floor it and merge leaving slower vehicles behind you with a crap situation.
Having a massive heavy steel box that weighs thousands of kilos that can accelerate that quick, that you can operate in public with little to no useful training is not safer. I'm sorry, no car outside of a race track needs to accelerate that quick. It's absurd.
The analogy fits perfectly. A slow car is also unsafe, that's why low speed plates exist along with minimum speed limits. There's no such thing as a vehicle with too much acceleration and never will be.
Having driven a very slow acceleration car, yes, yes you do, trust me. Nothing worse than merging into dense traffic with high-speed trucks next to you and not being able to come up to speed before the ramp ceases.
How much of that performance comes for free, from optimizing for range/efficiency?
What's the obvious "that could be less" in the system that wouldn't negatively impact efficiency?
None of it.
It the motor is smaller, it pulls less current.
If it pull less current, you can use batteries which aren't specced for high amps.

Weight has nearly no effect on range of an EV. The YouTube channel Aging Wheels has two good videos on this.
Here he talks about towing, and he demonstrates loading the truck to max capacity makes nearly no difference: https://youtu.be/UmKf8smvGsA
He also covered an attempted Cannonball run where they stuffed two extra battery packs into a Rivian R1T: https://youtu.be/yfgkh4Fgw98
Real differences makers are smaller wheels and aerodynamics

That's like asking if mommy needs a razor sharp knife in the kitchen or if we should keep it dull for legacy reasons.
Uhhh, what? No it isn't.
Having a sharp knife is safer than a dull one.
