How difficult was it in the past to start an old car using a crank handle? How could someone drive if they were too weak to crank it over?
Starting an early car wasn't just a test of brute strength—it routinely broke drivers' wrists. If you were too weak to risk a "Ford fracture," your best alternative was surprisingly modern. Before the electric starter became standard, drivers had to manually turn over the engine using a heavy metal crank at the front of the vehicle. The difficulty lay in fighting the engine's compression and the thick, sluggish motor oils of the era, which turned to molasses in cold weather. But the real danger was "kickback." If the engine's spark timing was set incorrectly, the fuel-air mixture could ignite too early, violently reversing the engine's rotation and ripping the iron handle backward. This backward snap was responsible for the broken wrists and snapped forearms that plagued early motorists. To minimize the risk, seasoned drivers learned to pull up on the crank in quick, sharp jerks rather than pushing down, and to keep their thumb tucked alongside t...
