The issue with the unattended gate is a problem. There needs to be someone there to man it, because there are many people that drive up to it without prepaying. Backing up is not the easiest (and most tolerating) thing to do.
Also, there needs to be a grace period for those that drive in and out. I had someone drive me to the terminal because of my excess baggage and we had to pay for being there for 10 mins.
