Perhaps something as simple as having a little video camera on bikes would discourage drivers from getting too close. If lots of cyclists had them drivers might start to move over a little more. Just knowing that you might be recorded could be enough incentive to a avoid cyclists.

I thought about having a small flag on a really sharp antenna-style post sticking on the left side of the bike. About a foot or two, laying parallel to the ground should do. That would encourage drivers to give a bit more room, as they are probably more afraid of getting their car scratched up then they are of hitting someone.

That still does nothing about the distracted driver. They aren't going to see the flag if they're looking down at their phone laughing and writing a text.

I think there is a range of tools that would making biking safer. I saw a lighting system that outlined a "box" around the cyclist. Some kind of automatic horn/led-flasher that would activate if a car got too close might be of some value.

I half suspect that might be construed as some sort of terrorist activity/behaviour.

Perhaps cities should build bike lanes.
