Let me further explain to you what is occurring here:
People on bicycles, without stopping, will ride from a sidewalk, across an intersection, 2 or 3 lanes per side here, fairly big roads. When you pull up to a light, you are watching for oncoming traffic in addition to any changes to the area you may turn into. A bicycle, who wasn't there and rides into an intersection with complete disregard for traffic or crosswalk signals can be in front of your car in a literal split second. If I wasn't looking before accelerating (I am in a manual car and have to put it into gear and all), I would simply run them over. Clearly, that isn't the case, but I imagine with the age of people here and the size of the vehicles they drive it is not an infrequent occurrence.
I'm really surprised how many people missed the sarcasm of my first sentence and literally the rest of the post...
I more than welcome you to come to my county, the most densely populated and poorly designed for any kind of walk ability and communicate to our various cities how to improve! Some spots such as St. Pete, Dunedin and a few other downtowns are walkable, but most of the area the residential zones are far from many other businesses and services, as least much to far to walk.
That isn't a joke when I say cities, as literally, you drive 10-15 minutes and you are in a different municipality controlled by a completely different governing body. We have a county wide public transit body, but each city has its own objectives and desires.
I am not oblivious to anything you are stating, but it is much more complex than stating obvious solutions we would all love to have. My work is a 25-30 minute drive, and the only public transit option is a bus, which takes 2 hours, not kidding!
Attempting to simply redesign a disaster that went from orange groves to wild urban sprawl necessitates funding on a variety of levels, state, county and local, and land that isn't readily available here.
