First off this looks cool.<p>But these 4G connected smart ODB dongles scare the crap out of me. You are giving an IOT device the ability to disable breaks, the transmission, and lock you inside. I'm not really worried about a Maximum Overdrive type situation, giving this much control to a category of devices that was able to take down Dyn because so many of these devices used a subset of 60 common factory default usernames and passwords.<p>I think there is a good use case for these type of devices, but I think ODB, isn't the right mechanism for it. But I don't know if there will be a new standard.
