It would be pretty nice in cruise servers, it's very hard to keep a certain speed with keyboard. I think a limiter would be good, just like the pit limiter but set for example at 100km/h. I think that would be good because you cant go through all corners at 100km/h, you have to slow down in some places, then you would just lift your foot off the gas, slow down, and then after the corner accelerate again, simple as that!
