"brakes make my car slower, so I'd expect my average velocity to decrease if you fixed them"

Just to be pedantic... in some contexts better brakes actually allow you to go faster. Consider racing on an oval track... a car with better braking ability can maintain speed longer as it approaches a corner, then scrub off speed more quickly to navigate the corner. A car with inferior brakes has to start slowing down sooner or risk crashing by taking the corner too fast. So better brakes can lead directly to faster lap times.

Yes, and in other contexts, better brakes make you go slower. Better brakes means bigger brakes: larger rotors (discs), larger and heavier calipers, etc. Larger brake rotors take more energy to accelerate (they're basically a bigger flywheel), so they decrease the car's acceleration. So if your goal is to have a car that accelerates as fast as possible, better brakes are actually a big detriment.

Indeed, disk brakes were first used on race tracks before being available on street cars.

And some people now argue that disc brakes on road bicycles are more dangerous because you learn that you can brake later and more suddenly. I.e You will more frequently approach the limit of friction between the (very narrow) tyre and the road.

Some people argue that the Earth is flat. That doesn't mean they have a good point.

The morons you're referencing probably think cars should all go back to drum brakes and bias-ply tires so people think more about brake fade and tire grip. It's an idiotic argument. Disc brakes on bikes are better in every way, except weight (they add about 1 pound, maybe). Reducing performance available to a cyclist doesn't make any sense at all; you never know when you're going to need to stop suddenly in the real world.

I had not heard that one. I always thought the main argument against disc brakes on road bikes was they they aren't good for long descents where you're riding the brake for long periods of time... due to heat fade or whatever.

Of course both things could be true...

No, you have it the other way around. Rubber brake pads on wheel rims fade with heat; disc brakes are able to dissipate far more heat, and are basically essential for long descents.

The only valid argument against disc brakes on bikes is that they weigh a little more (maybe 1 pound). I suppose you could also argue that brake fluid is more trouble to deal with than a cable, and certainly not as easy to jerry-rig, but hundreds of millions of cars use hydraulic brakes without any trouble these days, and I wouldn't want to have jerry-rigged brakes anyway.

Indeed. The insane thing about a modern F1 or LMP1 car isn't the acceleration (or at least not as much, the hybrid systems in a modern x car change that) but the braking.

Some drivers have complained about rain because the tears have been literally pulled out of them under the deceleration

I think dekhn may be making the same point, so no need for "Just to be pedantic." You raise an interesting factoid that many people probably haven't thought about, although it's pretty easy to intuit once you are encouraged to think about it.

No I wasn't making that point. The side-pedants talking about racing cars, those represent a tiny amount of braking activity compared to the total amount of braking activity across the world, so my statement about expecting the average velocity to go down still stands.

Also, I drift corners instead of braking, it seems to be a lot faster if you nail the tire orientation on the exit.

Fair point. As the old saying goes "looser is faster". The risk, of course, is that you wind up in the wall with your velocity = 0. :-)

In factorio the research you perform to get your trains to run faster is braking force research.

That's fine by me. I don't have a dog in that fight, so to speak...
