We do this at work (lots of sensitive data that we don’t want Openai to capitalize on) and it works pretty well. Hosted locally, setup by a data security and privacy sensitive admin, who specifically runs the settings to not save any queries even on the server. Bit slower than chatgpt but not by much
All of what the other two commenter’s said + the following:
The last one makes the difference in Munich between riding my normal bike and my ebike. With the mirror you see them coming, making it less uncomfortable when they pass + they automatically keep some more distance as they don’t want to hit the mirror.
Finally, depending on how fast your bike goes, look into tuning it to higher speeds? Mine is an s-pedelec and goes 45km/h, that means in city traffic I am able to swim with the traffic and not get passed often (this will probably trigger some debate and is a suggestion you should think about carefully, as it has other implications)
