[3] As auto racing strategies evolved from the early "go as fast as you can and see if you can stay on the track," Tetzlaff's success in the sport waned.
[1] On March 19, 1911, as Lozier ads claimed, a stock 49-horsepower (37 kW) model piloted by Tetzlaff set a world record for 100 miles (160 km) at 1:14:29.
He broke the world land speed record mark by running 142.85 miles per hour (229.89 km/h) on the Bonneville Salt Flats at Salduro, Utah, on August 12.
He even appeared in one Sennett film The Speed Kings (1913) alongside fellow racing driver Barney Oldfield.
Having recovered quickly, he resumed his racing career and was later engaged in the auto service industry but had to retire as his health deteriorated.
