Its nothing to do with the material, or sabots existing.
It about this account being a mishmash of fact, half-fact and made up BS.
I can see that if you only have a single rifle in one calibre which has to fulfil multiple roles then trick ammo may be the way to go.
A solid lead slug delivered by sabot might do it, lots of energy delivered to a window and dispersed safely as the lead splatters.
Equally it might just be counter productive, .22 is very small and penetrative - shooting clay pigeons with .22lr just produces a 0.22 hole and doesn't shatter the clay.
A soft lead pellet probably wouldn't do a lot of damage to a laminated or polycarbonate window, if any, however fast it was going.
Wadcutters actually just tend to punch a neat hole through things rather than spread out and transfer lots of energy.
A sensible option might be to use a soft-nose .308 round, or a 12 bore sabot slug, either would probably be overkill and potentially dangerous, arguable whether over or under would be worse.
I doubt a plexiglass window would deflect a 0.308 round significantly, not enough to be worth worrying about if the target is less than a metre behind, even at close range before the bullet is fully stable.
