Technology has made life so much easier for many, ABS is an example, before ABS drivers had to brake using a system called cadence braking. Cadence braking or stutter braking is a driving technique that involves pumping the brake pedal and is used to allow a car to both steer and brake on a slippery surface. It is used to effect an emergency stop where traction is limited to reduce the effect of skidding from road wheels locking up under braking. What are the odds that not many have even heard of cadence braking, let alone know how to do it?You can't brake on black ice - all you can do is steer!
Most cars on the North American continent have an automatic gearbox, like ABS that too has made driving so much easier and that too has been the cause of the loss of a very efficient way of slowing down without the use of brakes. It's called double declutching. The purpose of the double declutch technique is to aid in matching the rotational speed of the input shaft being driven by the engine to the rotational speed of the gear the driver wishes to select.
A vehicle can only travel so fast in a lower gear before changing up to a higher one, if you can bring the gear ratio down the car will slow to that gear's potential, you then repeat that with the next gear down, as you do the vehicle will go slower and slower. Along with cadence braking, double declutching was the way drivers slowed down in years gone by.
