Irony is,If Speed increases, Driver's concentration on the traffic HAS to increase. I always expect a "7½ moment" to happen anytime, whenever my Speedo goes above 120 kph. If i am NOT certain of my environment, my speed drops, automatically.
"Be prepared ... be prepared ... be prepared" is the ONLY Mantra for high speed driving.
If a Driver is not "100% sure of safety" AFTER completing a overtaking move, he should NOT overtake.
"Reaching destination an hour late" is more Comfy than wasting 'Time, Energy & Money' in a mini accident
Drive SAFE.
