What drivers used to know - let it roll on
It can happen quickly. You leave the light on or the battery fails after a few attempts to start because it no longer has enough juice. Not a big mishap in the past.
If there was a sloping road or a few strong helpers ready to push, the driver got behind the wheel, switched on the ignition, let it roll and engaged the clutch in second gear at a speed of 10 or 20 km/h. And the engine was running. And the engine was running. Most of the time, at least.
Today, this procedure is no longer included in any manual, because with the catalytic converter, the maneuver became a risk, as it would be possible for the mixture to ignite in the exhaust and thus endanger the exhaust gas purifier. Automatic cars are also less suitable for starting, so this old-fashioned way of getting a car to run has largely become obsolete. Some modern drivers have never done it or don't even know the procedure!
