@DominicRuffin8 Hi Dominic,
It depends on too many factors to specifically give an estimate on time or price. Please see this page which talks about developmental effort on different solutions: developer.uber.com/products/ride-…
Thanks!
@jonathonpitman Hi Jonathon-- I don't believe there is a good way in the sandbox API. In production API a ride cannot be booked if the user is already on a ride. Hope that helps!
@RobertKaliszuk Hi Robert-- It went through. If you have a contact at Uber Poland who you have discussed driver API access with, please have that person contact the Developer Platform team directly. Thanks.
