Transportation cyclist here. This is a great article, but it only indirectly touches upon one of the most effective tools a cyclist could have: an air horn. I have an Air Zound air horn and I feel much less safe riding without it. I'll often give a few toots before approaching an intersection to increase the chance that I am seen. And it has probably saved me from some major crashes when I lay down the horn on someon…
I'm not a cyclist, but I'm a huge fan of having these on bikes. They've become more popular in my area and because of that you notice the bicycles earlier so you have a much smaller chance of accidentally hitting them because you don't see them. After I started seeing these, I've become quite baffled why more cyclists don't use them. Also I wish that road vehicles had radios so drivers and riders could communicate in…
NO! Dear god no! Most people suck at communicating and could you imagine to road rage? Even though as a pilot you aren't supposed to chit chat on the radio I'm positive you've heard it.
Also you couldn't realistically set up something like ATC so you could have flight following. Not only would tracking that many vehicles be extremely difficult, but setting up all the transponders and receivers would be near impossible. You may notice you have a hard time talking to ATC below 1kft AGL. Plus everyone is in such close proximity at all times what are they going to do? "November 1234 Whisky, you have a Chevy incoming from your 6 oh clock passing on the left. Stay course." Or (in general channel) "Traffic at 6th and main, there is a cyclist approaching from the East on 6th, please use caution" and everyone that isn't at 6th and main tunes out, learning to tune things out.
Flight works because even at a busy airport the communication is still relatively small.
