> (I don't carry a window breaker/seatbelt cutter but it is a reasonable suggestion for everyone I think.) You can get keychain breaker/cutters if you want to be on the safe side.

If I'm reading the regs correctly, it may have become law in 2020 that all new cars use laminated side glass for at least the front row.
