I nearly knocked my teeth out with a ball pien hammer. With a normal, although forceful, hammering action I struck a car windscreen with it, the hammer bounced off and whizzed past my ear. The windscreen was undamaged.
For toughened glass you need a sharp and hard point. You can buy dedicated escape tools or as mentioned an automatic centre punch is reputed to work.
With a windscreen or other window with a rubber retainer you can push them out with your feet. Many are glued in now though and I have no experience of those.
