ELI5: Why is there still a need for a real-life person to come read gas and/or electric meters?

I work in the gas industry.  For right now, our customers have meters that are read wirelessly.  We still require a human to drive down your street so that their wireless unit can be close enough to pick it up, but we don't have to go up to your meter anymore.

Prior to that, it was simply the best way to have a tamper-proof system so that the meter would read the actual amount of power/gas and be reported properly.
