So there was some discussion up-thread about how owning a dashcam might negatively affect your insurance. I don't agree with that generally, (though insurance companies aren't known for being logical, so maybe...) but I have noticed something that you might not have.
You're showing speed information.
Speed limits notwithstanding - and I'm not a lawyer - if you're doing 29 in a 30 and you hit a kid that ran out between parked cars, or another car edging out of a junction, there is the potential that your adversary could get you for "driving without due care and attention". The speed limit doesn't protect you when the conditions don't support it. And as a side note, it doesn't save their life or your car, either.
Cpt. Buzzkill here would like you to think about the risks of self-incrimination. The dashcam is a powerful weapon in the fight against insurance fraud, poor driving and lunacy. But this isn't the USA; don't let your own evidence be used against you. Remember also that if you were maybe speeding before the accident, that could be taken into consideration.
