Uhhhmmm,
Probably it's just me? But Any bike, or wheel that would be Devastating (either emotional and/or financial) to lose, deserves better protection than a cable based lock.

If you don't feel the need lock up your home, if you are comfortable leaving the family auto unattended with the windows down, Then you are indeed fortunate to live, work, and shop in one of the few remaining Mayberry's left in this great nation of ours, And you Sir/Mam have my personal everlasting envy.

On the other hand if your community has it's share of crime, substance abuse/addiction, vagrants? If seeing a friend's or coworker's car windows down at work, coffee shop/diner, gym, or grocer causes even the slightest concern. Then you owe it to yourself to step up to a U-lock.

With your extremely desirable CAAD, Investing in an O.G. Bulldog Mini (or mini 7) if financially concerned, or Big K's Evo Mini (or mini 7) if you have the scratch, would be a smart decision. And the absolute minimum step I would take.
