Thank you for your time and insight Cscottdavis, appreciate it.
Thank you too Leisesturm & Korina. BTW-there are products in the market with sensors that warn the rider when a car is approaching and even have cameras to document it, they are very expensive of course and not priced for the casual commuter or pleasure rider riding in the street. Innovation/technology has advanced more than the childrens safety flag of old times. Of course no safety product can prevent selfish, unscrupulous inconsiderate drivers constantly looking at their cell phones, but that doesn't mean you shouldn't try by asking riders of their insight and experience to find something new, if it can save even only one life, it is still worth it. Presenting something new to city planners may implement new laws or required product. That's how seatbelts started, click it or ticket. If it doesn't work, you tried, some one else may come up with a better idea. Thank you for your time.
