IDEA: trip safer/safer trip by using a delayed ignition

Hi,
often it is the convenience that wins out when environmental considerations and the necessities fight each other when using the car. Whilst there was snow around and the car covered I found myself walking more for short trips to the shop since it appeared to be faster than getting the car out and drive worthy. This inspired an idea.

By introducing a "think pause" in the ignition cycle when the car was stopped for longer periods and 'cooled down' it may convince a person to do a local trip on foot or with the bicycle instead of using the car. The delay should be a minute or two, perhaps adjustable, where the drive has to have the key in the ignition but the car won't start.

This time forces the driver to think about taking the trip and/or to check over the car lights and other issues. An additional bonus of that a delayed ignition system may also prevent car theft as it takes a lot longer to start a car and drive off.
