Everybody knows the importance of not driving a car while drunk. Riding your bike while drunk is not a great idea either. Alcoho-Lock can help. It is a smart bike lock that checks your blood alcohol level and contacts your partner’s smartphone if it is too high. The companion app for the lock is available on Google Play. The idea sounds interesting, but it does not sound 100% foolproof. What do you think? Are you sold on this?
