At those speeds you have little room for error. Object in the road, pothole, whatever - Just twitch the wheel too hard & you're asking for trouble. A lane change is about all you can safely expect on a public road. Beyond that and your speed is over-taxing your tires, contact patch is very small so a bump or irregularity in the road is exaggerated. Get into an actual need to maneuver & it's all but over, friend.
