Now we have BS monitors we do not have to do the risky "look briefly in all mirrors about every 30 secs " thing.

If psychological buzzer distraction-risk
on a multi lane road exceeded risk of having my eyes off the road, I would include a gesture operated buzzer operation bypass system.

As the system uses the radar/anti collision, & we are advised not to mess with it, I am unsure about how to achieve the buzzer feature.
