After signing up my daughter up with a local driving school, we discovered that it was next to impossible to get an in-car appointment with an instructor. The appointments disappeared within minutes of being posted.
To solve this problem, I built a scraper that logged in to her account to check for available appointments, and would text me via Twilio if there were.
I set this program up on a cron job and let it run in the background each day while I was working.
It worked like a charm, and I was successful in getting her the required nine hours of behind-the-wheel driving time that she needed to qualify for the final drivers test.
