Rideshare with bidding - know your fare ahead, you choose it!
Customers sign up, enter destination and any notes: a stop at a drive-thru or I need a van. Drivers bid and customer accepts. Decision criteria can be lowest bid, or even preferred vehicle or driver...
Drivers are screened before given access, bid on fares. They can be part timers, limo or sedan drivers, as long as they're qualified.
