Wouldn't you have
more room if you get to speed quicker?
Apart from which, in a single panic stop where you realize you made a mistake, "bigger" brakes won't help you at all.
Stock model 3 with stock brakes and say 20" wheels to give us space for part 2.... and same car with the biggest brakes that'll fit under 20" wheels will both stop in
exactly the same distance with the same tires on the wheels.
The brakes don't stop the car, the tires do.
See also that $10,000 brake upgrade Porsche sells... that stops the car in
exactly the same distance the stock brakes do the first time. It's the 50th time in back-to-back-to-back abuse on a race track that those 10k brakes do anything useful.... and even then all they do is maintain that same-as-stock distance over more of those repeated abusive stops- they never, and can't, stop the car
shorter than the stock brakes could the first time
Well you're on to something there
better tires are the only thing that insures shorter stopping distances- they're what limits the cars ability to stop every time no matter how massive the brakes are.
Interestingly- Tesla didn't do so on the S or X though.
I mean, you factually don't, because that's not how physics works....
A car going 60 that got there in 3.5 seconds and then moves to the brake pedal, and a car going 60 that got there in 4.5 seconds and then moves to the brake pedal have
literally the same momentum
momentum is equal to mass times velocity. Both cars have the same mass (barring one driver being fatter I suppose...) and the same velocity. Therefore both cars have
exactly the same momentum.
And again, you're limited by the tires. "better brakes" won't help at all for street use since even the stock brakes can apply more force than the tires can use, and won't experience fade doing it.
No, it's a fact based understanding of how physics works, and pointing out that for people not taking their Tesla to a (non-drag) race track, a brake upgrade will do
literally nothing useful on the car.
For folks who
do intend to race the car on a track better brakes might well make a significant difference because unlike in street driving they will be repeatedly stopping back to back to back from high speeds....
(but even then the car won't ever stop shorter than it could the first time with stock brakes... it'll just maintain that distance over more heavy duty stops before it gets longer)
