How big is your bubble?
Safe drivers imagine a bubble of space around their vehicle which includes above, behind, to the sides and in front.
Depending on the road and weather conditions and the vehicle being driven, this bubble adjusts in size.
The only time it is as small as shown, is when parked. If moving with a small bubble, hoping nothing goes wrong is all that is preventing an incident.
The bubble needs to consider the ability to see hazards, the reaction time of all road users and the braking distance of all vehicles around you.
By having a bubble too small for the situation a driver risks not being able to stop in time, or being hit by someone else who cannot stop in time (like a large vehicle in your bubble that is too close behind you).
Driving too fast into a sharp bend (the road has a close vanishing point) essential bursts your bubble as you are travelling faster and require more distance to react and brake than the distance you can see ahead.
