A good, safe drive is about a mixture of techniques, but high on the list must be the need to use your vehicle’s brakes in a smooth and progressive way.
You can manage that by practising observation and anticipation, so you can begin braking at an early stage and leave a decent margin for braking more heavily, if the need arises.
Many drivers tend to brake too late and too hard.
Arguably less dangerous but equally annoying, some drivers have the habit of “comfort braking” — touching the brakes to enable themselves to feel better, even if they have no intention of slowing the car to any measurable degree.
They do so in the belief they are being careful drivers.
It is better by far to learn to read the road ahead; not only do you get early warning of developing hazards, you can respond by adjusting your speed using only your throttle.
Have you ever seen a “cascade” of brake lights ahead of you? An advanced driver will judge the speed and distances involved and, having left a decent gap, be able to follow in safety by letting the speed “fall away” and so avoiding the need to brake.
Think too about your positioning on the road. Can you maximize your forward view by putting your vehicle in a slightly different position on the road? This should not be an abrupt repositioning, but a smooth change in your line to enable you to see ahead that little bit better. Careful adjustment of road position improves the view ahead, particularly through corners.
