Tuning the radio wakes you up.
The theme from the jam was no text. That's why I couldn't explain anything. I agree with you though, a little bit of a hint would go a long way.
One more question concerning that; when the driver is in the process of falling asleep (the eyes start closing), I've tried messing with the radio, but it doesn't do anything (once the eyes start closing, they're going to close). Do I need to tune it to a specific frequency to keep the driver awake? By the way, thanks for the response. I appreciate it.
