Yeah, for the thief, maybe. This is a classic example of tech attempting to eliminate a mild inconvenience that no one really complained about before, and clumsily engineering a 'solution' that causes a dozen other novel and catastrophic problems in the process.
You meant a solution in search of a problem.
Not really, for some people it saves very little time, for most it's a small convenience, and for others it saves a lot of time, especially women who have their keys in their purse and don't have to search for them. Just because it's not useful to you doesn't mean that it isn't for others. Car manufacturers aren't going to change something for no reason unless people actually want it.
