I live in an area with 3 rivers and many streams. This calms that irrational fear of wrecking off a bridge and not being able to get out!
The Accutire Digital Tire Gauge is a great value for all the functions that it is capable of performing. We bought one for each car because of the emergency functions including the seat belt blade and window hammer.
I got this for my daughters car. Perfect size and weight. You never know when you will need this item to get out of a car window. I love the fact it has a built in razor blade to cut a seat belt.
