Re: add audio-comments/updates/street names
do you need to hear cars around you while cycling? Abso-fucking-lutely. You rely on your sense of hearing so much more, and given you're flesh surrounded by metal boxes travelling much, much faster, any extra help at judging how far they are from you, particularly approaching from the back, is a matter of life and death, potentially. I don't mean to say that you go out there on your bike every day thinking: this is gonna be the day I die, you're just aware of your chances against motor vehicles. Generally cyclists can calculate the odds well enough.
