So you believe taxi drivers never need to use taxis?

[nitwit005]

I rather clearly stated they would, just not much. The poor don't use taxis very frequently, as it's expensive to do so.

One taxi driver usually generates demand less than what one taxi driver usually supplies.

A taxi driver generates 8 hours per day of rides.

While taxi drivers sometimes consume rides, I can't imagine anyone thinks they consume 8 hours a day of rides?
