I don't agree. Looks like a Ford promo. The very basic of physics shows a direct dependency between how quickly car can accelerate to how fast it can stop. So faster car also stops better. In the very end, if the vehicle is balanced it's not a big issue. My Tesla Model Y performance that is doing 0 to 60 in 3.5 seconds stops immediately in any city environment. It has very small reaction distance. My old toyota wasn't able to do so. Thanks to wide tires and breaks that doesnt degrade as fast due to one pedal driving. One the highway the story is similar, yes the car can speed up faster, but it's up to a driver what is the final speed. My performance model is much more stable has far better and smarter control compares to almost any gasoline car. In the very end it quite often prevents many potential incidents.

This is funny considering multiple tests minus a few outlier publications have Tesla model 3's and Y's boasting some of the worst braking results of cars in their size category. Granted, maybe they've since changed the brakes as they frequently modify models.

By far the best control of any car is the driver, not some technical gimmicks. If you need a computer to drive safely to ie stay in the lane or keep safe distance from car ahead, there is the issue on your side. I've turned all of these off in my car, so that I know 100% the time I need to be aware of my surroundings and do decisions myself. Happily will accept full driving mode in 10-20 years, but anything in between has a lot of hidden pitfalls.

Not really. Generally a wide variety of cars will have a widely varying acceleration numbers (3x or more), but a pretty narrow (less than 1/3rd) spectrum of stopping distances. Physics it's just the friction coefficient of the tires, not car weight/tire diameter/tire width that matter. Sure real world considerations (like roads that aren't perfectly flat) do intrude a bit, but not much. Generally stopping distances (for modern vehicles) are related more to tire choice than anything else. Sure a stiff suspension helps minimize weight transfer and you lose less when a single tire hits a bump, but it's a small factor. Acceleration numbers can easily be a 3x difference, The slowest car in the USA is the Nissan Kicks has a 60-0 distance of less than 120 feet, even with crude drum brakes. A corvette with the special z51 performance package has a stopping distance of 108.4 feet. Sure if you stop 10 times from 60-0 without cool down, brake design and cooling make a big difference, but for normal road use (not racing on a track) it's not particularly relevant.
