Previously, I thought the most hilarious police vehicles were these NYPD Smart cars:

But if we travel farther back in time than 2017, to the 1960s, we learn that Port Authority cops in New York--those responsible for policing the tunnels in and out of town, among other facilities--once had to patrol the Holland Tunnel in these things:

The January, 1954 issue of Popular Mechanics reveals that the car is electric, and bi-directional:

The nearby Lincoln Tunnel, for reasons unknown, had tunnel carts of a different design. Rather than riding on rails, they were hooked to a low railing affixed to the wall:

This Lincoln design had sheet-metal sides and did away with the fancy canopy of the Holland design, though there are two adorable little semicircular windscreens:

And as you can see, these were not designed for plus-sized cops.

Incredibly, these tunnel carts persisted into the 21st Century; the New York Times reports that the last one was decommissioned in 2011.
