Speed Up Full Self Driving: Data Labeling While Supercharging

Today I was thinking if there is anything we can do to speed up full self-driving and it brought me to an idea.

From my very limited understanding of machine learning and listening to talks of Andrej Karpathy (Director of AI), it seems like data labeling is one of the most important aspects to the computer understanding how to drive itself.

What if Tesla makes an application on the touchscreen that enables us to label data of driving images (i.e. this is a stop sign) while supercharging. Maybe the amount of data labeled can translate into supercharging credits. It would give us something to do while charging and I'm sure many Tesla owners would be happy to do what they can to help move FSD forward. Tesla would get a lot more data labelers for very little cost.

I'm wondering your thoughts as maybe I'm missing something such as a touchscreen tablet not enabling specific enough labeling.
