Well, for 1.0 we clearly overdid it the other way around, didn't we? but take into consideration that these are not modern cars, and neither are the brakes. This is why they're not as sharp as modern day cars. We know how they should feel. Many among us have driven race cars now and even some do with the older ones.
Yes, not all of the cars lock up all of the time, but mostly do, especially on cold tires and brakes, or if you trail brake. This was exactly what we aimed for.
Be also aware of the brake overheating temps, cars do brake worse over 600ºC than when they are around 300. Just as they should IRL.
Also, did you notice that you can increase in almost every car the brake pressure value for having this effect? Right now they are set for the best compromise between being easy to modulate and believe it or not effective in braking distance.
I also hope that you are not using the brake pedal like a button. If so, you're only overheating the brakes and reducing the braking efectiveness. Usually up to 2/3rds of the pedal movement gives you the most effective braking and generates a bit less heat. Again, just as IRL.
And no, this will not be fixed in any update. We might just release a small patch for small bugs like one of the Mini's gear ratios bug and such, but nothing else. It's time to move on ;)
