Yes, they are lighter. No, they are not always both
lighter and more agile. They are certainly not more agile in all situations.
There is more mass in cars, but their strength-to-weight ratio is usually higher or much
They can accelerate faster. The strongest cyclists in the world can't do zero to sixty in less than six seconds. They can't beat a VW across an intersection, much less the many cars with more horsepower -- 200, 300, 400.... http://www.autobytel.com/content/res...til/listtype/9
I wouldn't call that more agile. The cars can get moving a lot faster, and that is one aspect of agility.
Another aspect of agility is how fast they can move left or right. A car traveling at speed can move left or right much faster than a cyclist can.
Especially when cycling at lower speeds (as when going up a hill), cyclists are slow -- and not particularly agile: slow to move forward or back, left or right. Again, not particularly agile, in the relevant senses of that word.
An inattentive or impaired driver who suddenly swerves while going 50mph (or 70, or faster) is far more agile, in meaningful or applicable or relevant senses of the word, than a cyclist.
However alert the cyclist may be, and however ready to act, there are situations in which things simply happen too fast and move too fast for his or her limited levels of agility.
