Well, about 10 years ago I got 3 street cleaning tickets, 2 parking tickets and my car was towed. Apparently I was not paying attention to street signs. I started thinking what do, how I can save myself from such a damage, money loss and frustration.
A year later I launched Xtreet in San Francisco and San Mateo: https://xtreet.com It helped me since to avoid any tickets since. And it’s been available for free to thousands of people. Saving hundreds of thousands of people to save millions of dollars and have better mood. A couple of years ago I added Online DMV services to Xtreet. No need to go to the DMV. People saving tens of thousands of hours from their smart phone or work desktop.
Enjoy!
