What I keep stating is my personal experience, a few years back back I was at the intersection of Southwest 107th Avenue and Southwest 84th Street (node 99259757) waiting to cross way 1103957961, the traffic lights for way 1132669471 had turned red but the signal for the pedestrians to go had yet to start counting down (at this intersection its like 5 seconds between the light turning red and pedestrian being able to cross as they give cars turning right from way 11160411 a little time to go before allowing pedestrians), there was a cop car on the lane closest to the sidewalk waiting at the stop line and a small family on bikes came behind me and waited behind me (the whole time on the sidewalk), it was at least another 2-3 seconds before the signal for pedestrians turned (the timer turned on) and the cop did nothing about the bikes even though they were clearly there. This was not the only time I saw bikes riding on the sidewalk as I was walking along, there are more instances of this happening then I can count. I have also done a little bit of research of my own on this matter as I have considered biking to the MDC Kendal, were I have classes, and I found nothing to show that pedestrians aren't allowed on sidewalks, and in fact from what I can tell in Fl bikes are fully allowed on sidewalks, they have to yield to pedestrians but they are legally allowed.
