Uh, no, because you will then get taxi drivers hacking the system,
spoofing taxis that are closer, and tying you up from across town just
so they can pick you up, with no regard for your real transportation
needs. The TAXInet should first signal all taxis in a one block radius,
then a two block radius, etc until a taxi locks on and verifies that it
is unoccupied. Location of the responding taxis should not rely on a GPS
set in the taxi, since that can be hacked. Rather, use a cellular
transponder that is triangulated by cell nodes.
