Add a cockpit to a Mercedes–Benz Silver Arrow and it turns into a speed record mecha with wheels. In October 1934, Rudolf Caracciola used this W25 to break the world record for the one-mile standing start. The same day, on a one-kilometer run, he became the fastest man on a public road, at 197 mph. That road, 30 miles south of Budapest, is still around. Traffic has slowed down.

197 MPH is pretty incredible today, much less in 1934. I have to wonder what in the world tire of that day they found to be capable of handling those speeds. Ze German automotive engineers (well, just all the German engineers of that era) were achieving some impressive things.
