A smartphone app recently launched can ask you if you really want to drive, if you have 'checked in' to a bar on Facebook in the previous while, writes Brian Byrne.
But that's just a small feature of the app, called Dash, which is mainly designed to make users more efficient drivers, and, ultimately, provide them with information about their driving habits that will help them decide what kind of car they need next time they go to buy.
Dash pulls together data from the car's own management systems as well as other information such as weather and traffic experience, and then creates profile information on the driver and vehicle which can be used both in real time and historically.
Dash requires a small device to collate and handle this information, which will then be managed via Bluetooth and the owner's smartphone.
One suggestion is that Dash may show owners that an electric vehicle is what they should be driving, based on the collected information.
Dash has been tested in a variety of cars, in the US, Panama, Canada, the UK and France. It will work in any car produced after 1996. It is currently available for Android phones.
