>>1076903There's no reason why you can't signal as part of riding defensively. You're presenting a false dichotomy

>or brake lights?Road bikes have some of the worst braking performance of any vehicle on the road and they travel relatively slowly. Other road users can also see clearly whether or not power is being applied. Basically, anyone who can derive useful information from a bicycle brake light is following too close to begin with.
