Yes initially this may seen creepy, but this is for your protection.
Not only from the sun but also the law.
You can ride your bike and record the trip and if anything happens then you are covered with evidence, the same thing goes if you are out and about, you can discretely record and then hand it over to the authorities to help with their investigation.
it is Bluetooth and you can hear you music as you go and connects with some phones for that cool hands free experience.
Never before is having video evidence ever been so important and who knows maybe you will pull off a cool trick and have a first person vid to upload for views.
