The best way to avoid being in an accident is to use safe driving techniques and always pay attention to where you are going and to other cars around you. However, despite your best efforts you are not in control of other drivers and sometimes accidents happen. Bummer.
There are options available on the market for vehicle escape devices which will help you out in case of an emergency, however a few of the models I have seen are designed to be placed under your seat or in the glove compartment. What these products do not address is that the location of these devices are often inaccessible after an accident or are thrown around the vehicle during impact.
This project will outline a design for a post-accident escape device which will never be further than your steering column. In the case of an emergency, use your good judgement to get yourself to safety.
Be smart and ensure your vehicle is equipped with all necessary safety gear such as tire repair, cones, and road flares. This project is part of a complete car survival kit.
Construct at your own risk.
statement of design:
The design consists of has a small blade located in a narrow channel designed to cut your seat belt should it become jammed, there is also a shard of ceramic which can be used to break your driver's side window allowing you to escape your vehicle if the door has become compromised. An LED can also be fitted allowing you some light if it's dark. The entire device has a non-slip grip made from a waterproof material and can be attached to your car key ring.

Enough talk, lets make something!
Step 1: Materials
- spark plug
- plastic (credit) card
- 2-part epoxy (or other strong adhesive, must be able to bind metal to plastic)
- permanent marker
- hobby knife with 'snapable' blade
- masking tape
- sandpaper (I used 3 types: 120 grit for wood, 120 grit waterproof emery cloth, and a stiff hobby board sander)
- vice grips (grips or clamps)
- drill (with metal bit)
Spark plug shards are also serious business, use goggles and gloves.
