just got it in today. i know "well if you're not a ******* crazy driver you shouldn't need it blah blah blah." i think the photo thing is usually absurd though because sometimes it's either slam on your brakes or just keep going and i choose to save my brakes and keep going because most of the time it's just being 1 or 2 seconds off and WHAM $50 (?) ticket in the mail.
anyways here's the picture i took:
found it for $16 on eBay
