I think this is a really great development for NYC! If they really do have crown vics running people around 800 million km annually... well damn substituting a japanese van in is a no-brainer! Imagine all the gas they'll save! Plus, this Nissan NV200 looks really appealing on the inside.
I wonder if we'll ever have larger taxis that pick up more than one party; like a bus but more personal. It could drive a limited distance off its route for your convenience and because there would be so many circulating you wouldn't need to wait very long to catch one at the corner. When I took the bus to work, it only came once every hour, and if I missed it I'd have to find an alternative route or call a family member or cab.
