You can’t feel the crack on the other side because the glass is a sandwich, two layers of glass with plastic in the middle – the plastic keeps shards of glass together in an accident.
Replacing glass around here (cenral Jersey) costs around $300 or so, and they come by your house or place of business and do it right there.
When my windshield was cracked two months ago I tried to get insurance to pay for it and found that since my deductable was $500, insurance wasn’t going to pay a dime. Oh well.
Funny thing is that I had another windshield broken 20 years ago and the replacement cost was the same (around $300), in the same state, with the same insurance company, same deductable, etc. and they paid it in full without charging me a dime.
