Car windshields should be made of Tempered Glass

[anoobindisguise]

Is your feature request related to a problem? Please describe.

Currently car windshields are way too fragile, because they are made of shitty regular glass - this isn't true in real life, as the front windshield is always tempered (car doors are made of regular glass so that you can break out of them and escape in an emergency, typically car going into deep water). This is especially bad because of the quirk where the left and right sides of the windshield above the front wheels can be easily broken giving zombies access to your vehicle despite those sections clearly having steel support structures that would be represented best by a quarterpanel.

Solution you would like.

We have actual tempered glass in game, so it would likely be not too hard to buff up the defense of car windshields and replace the constituent material, and optionally include an improvised windshield that is as fragile as car windshields are currently unless the current car windshields are actually meant to be as fragile as they are which also seems suspect.

Describe alternatives you have considered.

Tempered glass and reinforced glass sheets suffer from being made of normal "glass" which causes them to be instantly destroyed if the tile they're on is attacked. This system is already kind of weird (zombie smashes a glass jar of pickled meat inside a sealed refrigerator by bashing the fridge) but actual proper ballistic glass and whatnot definitely should be exempt from this particular behavior.

All windows on a modern car are made of tempered glass. The windshield is additionally laminated (has an inner layer of plastic and adhesive to hold it together when shattered)

Your assertion is incorrect. They're not weak because they're made of annealed glass, they're weak because the mostly arbitrary number assigned to them is too low.

What this needs is some attempts at objective measures of windshield and window glass ability to resist impacts.

Ok sure but how exactly would we obtain these measures and how would we measure? Would we just throw a ball at a glass and measure the velocity to obtain force and do this until we reach a point at which the glass breaks? Would that be an acceptable way?

We can use the measurements for 'common glass' and 'toughened glass' (tempered glass).

Tensile strength of the material is what we're looking for. Normal glass has a tensile strength of 40 MPa (N/mm²) which means it is load-bearing for up to 40 kg per mm. Tempered glass has between 120-200 MPa, hence 120-200 kg per mm. Taking a decent middle-ground of 160 kg per mm would be a sensible measurement hence.

Meaning it usually has around 4 times more durability then 'normal' glass.
