I didnt want to soak up what the Williams is about though! I wanted to know how fast it is and how well it handled and braked!
The thread was not just about these two cars, either. Read the title again.
NEW VERSUS OLD.
New cars, say 2002 onwards, versus old cars, 1982-1994, say.
Not just the Williams versus modern. That distorts the point. Because the Williams does get close, uniquely, among older cars.
Finally, having been a road tester, I quickly get the feel and get the performance of a car logged. I soon know what a car can and cannot do, my racing experience also helping, I suppose.
