A driver prefers to drive on a road so that the lane marking is at the center of the moving vehicle span. Indeed, many drivers seem to make an attempt to use the lane marking as a guide to keep the center of the vehicle right on top of the lane marking.An illustrative behavior arising from the use of the virtualization concept can be seen in the following style of driving.
A vehicle A is going on an undivided road 2-lane highway at a certain speed. (For planning purposes, the maximum speed you can expect on most Indian roads is 30Km/hour, and that is a separate subject). Another vehicle B close behind A determines that it needs to overtake A, unmindful of whether there is a vehicle C coming in the opposite direction in the other half of the road. You as a passenger in the vehicle B squirm in your seat. However, this is where virtualization happens! Thanks to the honking by vehicle B, drivers of vehicles A and C promptly swerve away from the median mark towards their respective shoulders and a clear virtual lane in the middle is formed for vehicle B. In other words, what was a 2-lane highway to begin with is now transformed into a 3-lane highway, the lanes now virtual.
Clearly, this is partly in jest, but you get the idea.
