The FastTrak lanes operated by Los Angeles Metro (the 10 and 110) are testing facial recognition cameras that can supposedly do the same job and ticket people automatically. I'm a little skeptical (on top of the privacy implications, there's practical ones: how well will they work when your passenger is reclining in the last row of a van with tinted windows? Or a child in a car seat facing backwards?), but we'll see how the pilot goes over the coming months.
