There's other ways to get local traffic data, too. For instance: Traffic Message Channel, which can be broadcast with RDS on an FM station, exists.

As long as stations persist that transmit the data (it's sent over RDS), then it will continue to work. There's no subscription involved (or at least, there isn't for my car -- it works where it works, and there's no mechanism by which to pay for using it).

The Wiki has some further reading on the technology: https://en.wikipedia.org/wiki/Traffic_message_channel
