Not So Fast!

Stanley Valinski patented this “man-catching tank” in 1921, “for use in banks for catching and holding burglars or the like.”

The steerable armored enclosure sits in the lobby with a watchman inside. If the bank is robbed, the watchman pushes a button to summon the police, then drives the tank to block the door, where he can cover the bandits with a gun or grab them using the angle frames.

It’s remarkably well thought out: There’s even a separate hatch by which bank officials can enter the tank if the watchman is shot. Probably best not to mention that in the interview.
