I mean technically you are correct, but usually when people talk about performance, they are considering the recreational qualities of the car. most people don't buy fast cars to shave fractions of a second off accelerating to 35mph.

Save travel time by accelerating fast? So you get to 40mph a half a second faster? Are you being sarcastic?

Or arrive faster at the next red light.

I used to think this until I got an EV. The ability to a) accelerate quickly and b) stop more quickly makes them almost like motorcycles.

You catch lights easier, merge effortlessly and slowdowns are zen.

I gain about a couple of min trip time to drop off my kids which is about 10m and 6-7 signal lights away.

Also on highways I utilize the HOV lane which for me trims about 5m off my longish commute.

And it’s all comfortable and silent.

Ignoring the existence of traffic, sure.
