Highly recommended! On 04/06/18 I had a rollover accident with my 3 month old baby. By the grace of God we are doing well. However, we landed headfirst. I remembered having a life hammer in my glove compartment. I was able to unbuckle my seat belt and get it. I smashed the passenger side window with it and was able to crawl out. In the future I would recommend putting a velcro strap next to the driver's seat and the others in the glove box. Because if my seat belt didn't naturally come undone, I wouldn't be able to stick my life hammer in the glove compartment to cut it. If you don't have an ignition lock, I would also recommend getting one that attaches to your keys.
