in addition we won't be able to get realtime speed data from the taxis. initially we had the capacity with here on board devices to be able to see how fast a taxi is going at any particular moment. we will be able to get to speed data, but it requires an extrapolation of the smaller data set we have so as we see a taxi moving between these 20 seconds pings we can calculate how fast they're going, but it won't be as robust as if we had it through the on board devices. but we have the data we need for a lot of functionalty, but the functionalty that we don't have at the moment is the data set necessary to move forward with the implementation of an eta system, to provide our taxi data to private app developers to build e hail platforms on . the good news is that while we're going through this process, the e hail platforms available in san francisco have been signing up more drivers and vehicles. i think that's really great news for the public because that means if you have an adequate supply of taxis on any particular smart phone app, you have an hope for su
