No, obviously it is just different system of brakes. You can't use it. The only braking is: engine braking, tire rolling resistance, aerodynamic drag, scrubbing of tires during understeer or oversteer (I guess more likely understeer in this challenge , oversteer is for evasive actions). You can also try swerving left to right technique by which you also scrub off speed into the slip angles and by increasing travel distance, but it may unset you from the proper turn in. No just no parking lots, an oval is bascially a parking lot too, with heavy cambers on its ends, and runway at the airfield is also bascally a big parking lot just with a bit more serious engineering going on underneath it The airfield based circuits that you mentioned are awesome choices actually.
These kind of challenges don't make me proud about anything Just thought it would be fun to try out sometime in between serious races. Juts thought i'd ask because you only stated the use of the brake pedal. But yea, your loss.
Just remembered something I tried years ago - assign your steering backwards. Considered a fun race in the league with everyone doing the same, but, well, obviously easy to cheat that one. *And on a related note, when I was making and trying the headtilt plugin I discovered you could end up with an upside down view. Cue a lap or two driving like that, as well.
Yesterday I ended up upside down in LFS ( I use VR) and it already was weird. Let alone if you did that while actually driving! XD I'd throw up
The difference about no brakes challenge, is that it gives you useful skill - to drive fast in case your brakes fails. So this challenge is very practical actually. Can think of way more extreme situations which it is possible to get into while racing, and to make it a challenge with a purpose of practicing for that. Slicks in the rain ? Saving fuel ? Interestingly I just thought that no brakes challenge eventually could possibly mean saving fuel too, because of amount of coasting.
