[Healeys] Windshield

[Oudesluys]

"Modern" glass of a laminated construction has a much softer outer glass 
pane compared to the old fashioned hardened single panes. I have the 
impression that the last 25 odd years the outer glass is even softer 
than the first generations of laminated windscreens. It has to do with 
the prevention of shattering into a million pieces and thus completely 
obstructing the vision as happened with the hardened glass.
If a laminated screen is hit by a small stone it may crack when the 
glass is to hard, so I presume they made it softer to prevent cracking 
but the result is that pits are formed easier and wiper scratches are 
more common.
This is what I presume, but there may well be other causes.
