Christina Cook often rides her bike from her home near downtown Orlando to day care, where she drops off her young son. She prefers the bike to the family car, a 2003 Camry with almost 200,000 miles on the odometer.
 
 “We enjoy it [biking],” she said. “I’ve never felt I was inconvenienced.”
 
 Cook, 26, is like a lot of her contemporaries, the generation of millennials who are not as enamored with the automobile as their elders — who flocked to the internal-combustion engine as a symbol of freedom and a passport to far-flung suburban homes.
 
 A recent study by the nonprofit consumer group U.S. PIRG based in Boston found that millennials — or those born roughly from 1983 to 2000 — are driving less in favor of walking, biking and catching the bus or train, if one is available.
