“The Wait Is Over,” a sponsored Gothamist post about Nissan taxicabs trumpeted yesterday: “NYC’s New Cabs Have USB Chargers, Passenger Climate Control, Panoramic Glass Roofs.” But after we got to the bottom of the post promoting Nissan’s #HailYes campaign, we wondered: where are these wondrous vehicles? Well, only about 12 of the city’s 13,237 cabs are Nissan NV200s. But Nissan’s still pushing a giant #HailYes social media campaign.
