I've definitely heard organic stories from people who got favorable insurance/legal outcomes after a traffic accident because they were using a dashcam. Generally, if you're not doing anything wrong, it is a good idea to record whatever you're doing, because it's proof that you're not doing anything wrong (police departments use this to great effect; they love bodycams in 99% of cases, and simply turn them off when they're about to do something that they wouldn't want to have a bodycam for). The negatives are second-order effects that only come about when everyone is doing it.
