I don’t understand what people’s problem with this is. You drive up, press a button, take your ticket and the barrier lets you in. On the way out if both cameras read your number plate correctly it opens automatically to let you out. If it doesn’t open, put your ticket under the laser and it opens. What’s hard about that? I’ve been through hundreds a of times and never had a problem, although I did see the barrier come down on someone’s car once but that was their own fault for stopping under it.
