When I first started riding a street bike (@14), my mother was worried about an accident. A guy she worked with (who also rode) reassured her by telling her that bike riders become much better drivers because they learn to stay aware of their surroundings at all times and those skills carry over with them when they are driving their cars. That was almost 40 years ago. The fact that this thread exists today proves that it's still true.
Mom still worries though and I won't even go into the chaos that ensued when Dad bought a new bike @ 80.
