No, but, they track acceptance % by drivers so a driver that is screening locations like that will put themselves at risk of being kicked off Uber. The expectation is that the acceptance % is very high and that once a fare is accepted it is 100% carried out. Also when they display a potential fare to a driver they only show an estimate of how far away it is in minutes and a very zoomed in map of the location so it is hard to even know where you are going to be headed exactly before you accept.
