Given the lower rate of speed and lack of licensure requirements, it might seem that hopping aboard a bike after a couple drinks would be a better idea than driving — but it's still dangerous, not to mention illegal. The Alcoho-Lock is a new gadget designed to help prevent this reckless behavior. To use it, you need to breathe into a sensor hole on the side of the device. If it detects an illegal amount of alcohol on your breath, it won't unlock, and will also use the companion app to ping a spouse/friend/family member with your location to let them know that you're going to need a ride.
