Interesting indeed. They can just plug in and invite themselves to all your data on the spot?
In the states they’d have to get a search warrant either way, bike or helmet mount. Then if they actually went that route and put forth the effort to present it to a judge, you’re probably already in some pretty deep do-do. Like, just killed someone or had a kilo of dope in your backpack deep do-do. They have to articulate probable cause and with some exceptions, judges won’t sign warrants over petty traffic BS. 4th Amendment issue.
I just went the Quad Lock/iPhone route with an arm extension and vibration dampener. Works like champ for now. Quad Lock is constantly coming out with new accessories too. I’ve had my eye on some these dedicated camera systems for a bit though. I’m trying to abstain from my gear and gadget habit for the time being. Some examples in here I’ll eventually give a look.
