Most riders don't realize they're being overcharged with Uber's new upfront fare.
In addition the driver is not entitled to any portion of the overcharge.
The rates are way too low for drivers. Drivers have so much cost tied up in vehicles, insurance, gasoline, time, maintenance, customer service and risk, that it is simply just not worth the effort.
Uber will show the rider one charge but the driver never actually sees what the rider paid. But, of course, rider and driver frequently compare the discrepancies which show the gross overcharges. Uber is the most greedy scam company ever. They ought to be investigated at the highest levels.
When new rideshare services come along please be sure to sign up for those instead.
