Yeah, this is for tempered glass, it might/will be a bear to try to escape in a vehicle that uses laminated glass during an emergency.
Im just unsure how many vehicles use laminated glass, if you do have one that does, the other device pictured here that looks like a pointed axe kept under the seat would be more fitting for the job.
