On the circular road, did you try clicking a single vehicle to slow it down just a tad? I did that (just one vehicle) and watched in horror as a phantom jam developed. Just 2 slow vehicles and there arose a bumper-to-bumper, wave of stationary cars.

This is why keeping distance and decelerating slowly is important (also saves your brakes and uses less fuel)

Alternatively, this is why not being that person going slower than the rest of the traffic is important.
This is a slippery slope. At least this puts pressure onto people to match the speed of people going faster. So this might lead to massively increased average speeds risking an increase in accidents.
Wouldn't it?

No, because average speed doesn't increase the number of collisions as much as speed differential does.
If everyone is going 70 mph, it's quite safe. It's the one moron going 50 mph or the one asshole going 90 mph that will cause the crash.
If you drive 100 and the limit is 100 you are perfectly fine. Anybody who goes over the limit has to live with the fact that many people stay within the limit.
I always do this but my mechanic is complaining that I have to use the breaks, they rust fast if not.

I am no mechanic so I don't make money from selling you new brake rotors, but I think coming to a complete stop a few times each drive should be more than enough to brush any rust away.

Depends on local weather conditions. Anywhere that road salt is used in winter, some hard braking regularly is extremely beneficial. Road salt is not only corrosive, it's also hygroscopic, so you really want to clean that shit off.
As for wearing out brake rotors prematurely - even with aggressive braking they last more than 50k miles. So on average you'd replace them less often than every 5 years, and they cost around around $250 for a set of four. Doesn't seem like a very good get-rich-scheme for the mechanic.

This. No mater how minimally you try and use them brake rust will not be a problem on a car that's driven at least weekly.
This depends largely on where you live. Salted roads are ready break-killers. If the car stands still a month and the breaks wasn't clean, there might be holes when you want to use the car again. I know, tried it a few times with my cars over the last 30 years. Repairing that can be expensive depending on car :-)
