I wish that at intersections where they install beg buttons, they would install some type of overhead sensor for determing when a cyclist is at the intersection. I also wish that when they provide extended green signals for cars "pulling up" to the intersection from a ways back, that they'd also provide extended greens for pedestrians who hit the button just after it turns green.

Also, on some signals the green left turn arrow goes off first while the light is still red, but if the pedestrian presses the button during this phase they are still left out completely on the green phase. What is up with that?

What if people in their automobiles had to press beg buttons or turn their radio to a particular frequency (displayed on an overhead electronic sign) to signalize their presence at an intersection? Let's put everyone on the same level.
