I bike at night often. Very few turn off their blinders for me. It’s so bad that I have to come to a full stop until the car passes. If you have ever turned off your blinders for bikers at night: Thank you, seriously. We appreciate it more than you know.
I’m the creator of this list of open source software. Most of what is on there is stuff I use. The list, unlike others, tries to factorize user experience into the mix, so one could realistically use all the software there. There are a few proprietary options in the mix, but those simply have no open source alternative.
